If a port defines MICROPY_SOFT_TIMER_TICKS_MS then soft_timer assumes a
SysTick back end, and provides a soft_timer_next variable that sets when
the next call to soft_timer_handler() should occur.
Otherwise, a port should provide soft_timer_get_ms() and
soft_timer_schedule_at_ms() with appropriate semantics (see comments).
Existing users of soft_timer should continue to work as they did.

Prior to this change, after calling connect() the status() method for the
STA interface would either return STAT_GOT_IP or STAT_CONNECTION. The
latter would be returned because wifi_sta_connect_requested==true and
conf_wifi_sta_reconnects==0 by default. As such there was no way to know
anything about errors when attempting to connect, such as a bad password.
Now, status() can return STAT_NO_AP_FOUND and STAT_WRONG_PASSWORD when
those conditions are met.

In ESP-IDF, enabling SPIRAM in menuconfig sets some Kconfig options:
- "Wi-Fi Cache TX Buffers" enabled. By default this tries to allocate 32 of
these when Wi-Fi is initialised, which requires 54,400 bytes of free heap.
- Switches "Type of WiFi TX buffers" from Dynamic to Static. This
pre-allocates all of the Wi-Fi transmit buffers.
Not a problem if PSRAM is initialised, but it's quite a lot of RAM if PSRAM
failed to initialise! As we use the same config for PSRAM & no-PSRAM builds
now, this either causes Wi-Fi to fail to initialise (seen on S2) or will
eat quite a lot of RAM.

In commit 7c929d44 the console UART was changed to use the UART HAL.
Starting the UART HAL will change the UART clock from whatever it was
already configured at to UART_SCLK_DEFAULT. There is no "initialize at
existing settings" option.
This clock doesn't work with DFS.
The ESP-IDF code already takes this into account, and when DFS is enabled
it will configure the console UART to use the correct platform-specific
clock that will work with DFS.
The UART HAL init undoes this and sets it back to default.
This change will query the clock before the HAL init, then use the HAL
function to restore it back. Thus keeping the clock at the "correct"
value, which depends on platform, DFS status, and so on.
The clock frequency will be found using the UART driver function ESP-IDF
code uses for this. The existing code hard-coded a path that worked if the
clock was the APB clock and would fail otherwise.
The UART_NUM_0 define is removed because driver/uart.h already provides
this same macro.

LWIP doesn't implement a timeout for blocking connect(), and such a timeout
is not required by POSIX. However, CPython will use the socket timeout for
blocking connect on most platforms. The "principle of least surprise"
suggests we should support it on ESP32 as well (not to mention it's
useful!).
This provides the additional improvement that external exceptions (like
KeyboardInterrupt) are now handled immediately if they happen during
connect(). Previously Ctrl-C would not terminate a blocking connect until
connect() returned, but now it will.

the Arduino Portenta H7 is reported as PORTENTA which is unfortunate as now
there is another Portenta board (Portenta C33) supported in MicroPython.

missing MICROPY_PY_NETWORK_HOSTNAME_DEFAULT identifiers.

If you have a variable frequency and pulse width, and you want to optimize
pulse resolution, then you must do a calculation beforehand to ensure you
normalize the array to keep all list values within bound. That calculation
requires RMT.source_freq(), RMT.clock_div(), and this 32767 constant.
Signed-off-by: Mark Blakeney <mark.blakeney@bullet-systems.net>
To create an esp32.RMT() instance with an optimum (i.e. highest resolution)
clock_div is currently awkward because you need to know the source clock
frequency to calculate the best clock_div, but unfortunately that is only
currently available as an source_freq() method on the instance after you
have already created it. So RMT.source_freq() should really be a class
method, not an instance method. This change is backwards compatible for
existing code because you can still reference that function from an
instance, or now also, from the class.

This change:
- Has a small code size reduction.
- Should slightly improve overall performance. The old hook code
seemed to use between 0.1% and 1.6% of the total CPU time doing no-op
calls even when no USB work was required.
- USB performance is mostly the same, there is a small increase in
latency for some workloads that seems to because sometimes the hook
usbd_task() is called at the right time to line up with the next USB host
request. This only happened semi-randomly due to the timing of the hook.
Improving the wakeup latency by switching rp2 to tickless WFE allows the
usbd_task() to run in time for the next USB host request almost always,
improving performance and more than offsetting this impact.

The main motivation for doing this was to reduce the latency when the
system is woken by a USB interrupt. The best_effort_wfe_or_timeout()
function calls into the pico-sdk dynamic timer framework which sets up a
new dynamic timer instance each time, and then has to tear it down before
continuing after a WFE.
Testing Python interrupt latency, it seems to be improved by about 12us
(from average of 46us to 34us running a Pin IRQ). C-based "scheduled
nodes" should see even lower latency.

Update rtc, machine and powerctrl drivers to support STM32H5 sleep
modes. This makes RTC alarm wakeup working from lightsleep() and
deepsleep().
Changes:
- Determine start reason for machine.reset_cause() in modmachine.c.
- Add proper interrupt clear code in rtc.c.
- Add wakeup functionality in powerctrl_enter_stop_mode(). Remember
and restore voltage scaling level. Restart HSI48 if it was on before
entering sleep mode.
- Clear DBGMCU_CR in SystemClock_Config() as for other variants.
Otherwise debug flags prevent entering sleep mode.
Implementation Notes:
- rtc.c: EXTI_RTSTR1 bits are not present for H5. Code sequence from
G0/G4/L4/WB/WL would be invalid. RTSTR is only defined for external
(GPIO) interrupts. Maybe this is also true for other STM32 variants.
- powerctrl_enter_stop_mode() uses complicated, nested conditionals
to select STM32 variants. To make code slightly better readable,
comment have been added. A non-nested, #if/#elif sequence would
make the code more readable. I leave this to the original authors.
