This commit is a no-op change to simplify existing config.

Whole packets are now pushed up to the higher layer of the BLE stack,
instead of buffering the packets so individual bytes can be requested.

This can improve efficiency for Bluetooth systems that already process
whole packets at the lower layers.

The nxp_driver v2.10 allows for/requires some changes to the code:

- Remove some part of pwm_backlog.*, which is provided by the lib now.
- Change eth.c: the newer versions have additional parameters of the
  library versions.
- Change sdcard.c: use TransferBlocking instead of TransferNonblocking.
- Add some support for the MIMXRT1176 device.
- Set the clocks for UART, I2C, Timer.
- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI.  It's faster and interferes less with
  other modules.
- Use the clock_config.c files of library v2.8.5.  The mimxrt files keeps
  the clock_config.c files from Verson 2.8.5.  With clock_config.c from
  v2.10, the boards do not work.  Refactoring of the clock set-up is on the
  to-do list.
- Enable expiry timers for UART, I2C and SPI, avoiding a stall in library
  code.
- The clock_config.* files are moved from the board-specific directories to
  the boards directory and given a MCU related name.

This fixes the cases where the task being waited on finishes just before or
just after the wait_for itself is cancelled.

Fixes issue #8717.

It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

This cleans up the parsing of MP_REGISTER_MODULE() and generation of
genhdr/moduledefs.h so that it uses the same process as compressed error
string messages, using the output of qstr extraction.

This makes sure all MP_REGISTER_MODULE()'s that are part of the build are
correctly picked up.  Previously the extraction would miss some (eg if you
had a mod.c file in the board directory for an stm32 board).

Build speed is more or less unchanged.

Thanks to @stinos for the ports/windows/msvc/genhdr.targets changes.

This gives more information to the user when doing updates from SPI flash.
Signed-off-by: Damien George <damien@micropython.org>

The following changes are made:
- Use software SPI for external SPI flash access when building mboot.
- Enable the mboot filesystem-loading feature, with FAT FS support.
- Increase the frequency of the CPU when in mboot to 96MHz, to increase the
  speed of SPI flash accesses and programming.

This allows a board to modify initial_r0 if needed.

Also make default board behaviour functions always available, named as
mboot_get_reset_mode_default and mboot_state_change_default.

I2C transfers are much more efficient if they are combined, instead of
doing separate writes and reads.

Fixes issue #7134.

This option is useful for ports where it's more efficient to do a full I2C
transfer in one go.

The procedure given here will work whether or not the DevKit motherboard is
used and is equipped with the support MCU.  It is laborious but works.

This shortens the quickref.  Also change the note about the hardware SPI
frequeny limits.

And make it so this test can run on any target.

LED and time testing has been removed from this test, that can now be
tested using: ./run-tests.py --via-mpy --emit native.

This follows on from a5324a10 and allows
mpy-cross to dynamically select whether ARMv7-M instructions are supported

The config option MICROPY_EMIT_INLINE_THUMB_ARMV7M is no longer needed, it
is now controlled by MICROPY_EMIT_THUMB_ARMV7M.
