The code did not check at deinit whether a UART was initialized. That did
not matter for all MCU's except MIMXRT1176, which crashes at the second
soft reset in a row.
But since it is a general problem to use UART methods of a UART which has
been deinitialized, checks were added to all applicable methods for a clear
response instead of e.g. a crash.
Deinitialize UART using software reset. It resets the UART but keeps it
accessible for software, avoiding an exception when UART registers are
accessed after a DeInit.

This commit adds the necessary configuration and hooks to get the CYW43
driver working with the mimxrt port.
Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
This is a basic SDIO driver for the mimxrt port, that was added mainly to
support the CYW43 WiFi driver, and as such it only supports the commands
required by the CYW43 driver (but more commands can be added easily). The
driver performs non-blocking DMA transfers, and can detect and recover from
errors.
Note: because the mimxrt port is missing static alternate functions, named
pins and other pin related functions, currently the alternate functions for
USDHC 1 and 2 are hard-coded in the driver.

Add portable pin config macros to mphalport.h. And add a function to
configure pins with more pin options such as alt function, pull, speed,
drive, interrupt mode, etc.
Note: this new `machine_pin_config()` function can replace
`machine_pin_set_mode()`, but the latter is left as-is to avoid breaking
anything.

The rp2 port was enabling SSL and had finalizers enabled via the "extra
features" level, but missed explicitly enabling `MICROPY_PY_SSL_FINALISER`
(like esp32, stm32, and mimxrt did).
This commit makes `MICROPY_PY_SSL_FINALISER` default to enabled if
finalizers are enabled, and removes the explicit setting of this for
esp32, stm32, mimxrt (because they all use the "extra features" level).

It should be that:
- duty_u16=0: output low, no pulse
- duty_u16=65536: output high, no pulse

This commit:
- Finds a common set of board feature tags and maps existing features to
that reduced set.
- Removes some less-useful board feature tags.
- Ensures all MCUs are specified correctly.
- Ensures all boards have a vendor (and fixes some vendor names).
This is to make the downloads page show a less intimidating set of filters.

Previously this was explicitly enabled on esp32/stm32/renesas/mimxrt/samd,
but didn't get a default feature level because it wasn't in py/mpconfig.h.
With this commit it's now enabled at the "extra features" level, which adds
rp2, unix-standard, windows, esp8266, webassembly, and some nrf boards.

Three bugs have been fixed in this commit:
1. When the duty was set with duty_u16(), changing the freq with pwm.freq()
would not keep relative duty rate, but the absolute pulse duration.
2. Fix another inconsistency when displaying the PWM pin's properties of a
QTMR channel.
3. Improve the error checks for the second channel being a PWM pin and pin
pairs to be a FLEXPWM A/B pair.

It was treated as an error before. The error surfaced when using the
NINAW10 drivers for WiFi support. Even if this is a bad behavior of the
NINA driver, machine_spi can be forgiving in that situation.
Separate low level flash access from mimxrt flash driver object. Allows
better abstraction from hardware for testing and reuse in other areas (e.g.
bootloader).
