When MICROPY_PY_MACHINE_I2C_TRANSFER_WRITE1 is enabled the port's hardware
I2C transfer functions should support the MP_MACHINE_I2C_FLAG_WRITE1
option, but software I2C will not. So add a flag to the I2C protocol
struct so each individual protocol can indicate whether it supports this
option or not.
Fixes issue #8765.

Catch calls to legacy:
MP_REGISTER_MODULE(name, module, enable)
Emit a friendly error suggesting they be rewritten to:
MP_REGISTER_MODULE(name, module).

* The mbedtls config file path is hard-coded to the config file in
the stm32 port. Any port using this cmake fragment is not actually
using its own config file.
For v2 cards that are standard capacity the read/write/erase commands take
byte address values. Use the result of CMD58 to distinguish SDSC from
SDHC/SDXC.

For CSD v1.0 the computed size is in bytes, so convert it to number of
512-byte blocks, and then ioctl(4) will return the correct value.
Also implement ioctl(5) to return the block size, which is always 512.

Both led_init and led_state are configurable via MBOOT_BOARD_LED_INIT and
MBOOT_BOARD_LED_STATE respectively, so don't need to be MP_WEAK.
Furthermore, led_state and led0_state are private to ui.c so can be made
static.

This IO was enabled in IDF commit 68f8b999bb69563f2f3d1d897bc073968f41f3bf,
which is available in IDF release v4.3.2 and above.

This tests the build when -O2 is used, which can lead to additional

This file is not executable so shouldn't have the shebang line. This line
can cause issues when building on Windows msvc when the PyPython variable
is set to something other than "python", because it reverts back to using
the shebang line.
The top comment is also changed to """ style which matches all other
preprocessing scripts in the py/ directory.

Without this, newer versions of gcc (eg 11.2.0) used with -O2 can warn
about `q_ptr` being maybe uninitialized, because it doesn't know that there
is at least one qstr being written in to this (alloca'd) memory.
As part of this, change the type of `n` to `size_t` so the compiler knows
it's unsigned and can generate better code.

Otherwise include directories are added unconditionally to the build
variables if the component (submodule) is checked out. This can lead to,
eg, the esp32 build using lib/lwip header files, instead of lwip header
files from the IDF.

System config block contains hardware unrelated to USB. So calling
`__SYSCFG_CLK_DISABLE()` during `HAL_PCD_MspDeInit()` has an adverse effect
on other system functionality.
Removing call to `__SYSCFG_CLK_DISABLE()` to rectify this issue.
This call was there since the beginning of the USB CDC code, added in
b30c02afa0.
According to ST Errata ES0206 Rev 18, Section 2.2.1, on STM32F427x,
STM32F437x, STM32F429x and STM32F439x.
If the system tick interrupt is enabled during stop mode while certain
bits are set in the DBGMCU_CR, then the system will immediately wake
from stop mode.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.
According to ST Errate ES0394 Rev 11, Section 2.2.17, on STM32WB55Cx and
STM32WB35Cx.
If the system tick interrupt is enabled during stop 0, stop 1 or stop 2
while certain bits are set in DBGMCU_CR, then system will immediately
wake from stop mode but the system remains in low power state. The CPU
therefore fetches incorrect data from inactive Flash, which can cause a
hard fault.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.
This was added by mistake in 8f68e26f79 when
adding support for G4 MCUs, which does not using this get_bank() function.
FLASH_OPTR_DBANK is only defined on G4 and L4 MCUs, so on H7 this
FLASH_BANK_2 code was being wrongly excluded.

The callback passed to add_alarm_in_ms must return microseconds, even
though the initial delay is in milliseconds. Fix this use, and to avoid
further confusion use the add_alarm_in_us function instead.
