This adds a rule to cover all ports/**/*.[ch] file to the code formatting
list. Explicit exclusions are also added for code in ports/ which is third
party, or which requires a lot of reformatting.

To avoid any I/O glitches in mp_hal_pin_config, make sure a valid alternate
function is set in AFR first before switching the pin mode. When switching
from AF to INPUT or OUTPUT, the AF in AFR will remain valid up until the
pin mode is switched.
This commit adds support to the parser so that tuples which contain only
constant elements (bool, int, str, bytes, etc) are immediately converted to
a tuple object. This makes it more efficient to use tuples containing
constant data because they no longer need to be created at runtime by the
bytecode (or native code).
Furthermore, with this improvement constant tuples that are part of frozen
code are now able to be stored fully in ROM (this will be implemented in
later commits).
Code size is increased by about 400 bytes on Cortex-M4 platforms.
See related issue #722.

On ESP32 S2/S3 variants, GPIO0 through GPIO21 are valid RTC pins. This
commit defines the valid RTC_VALID_EXT_PINS for the S2/S3 variants,
otherwise, it keeps functionality the same.
For ESP32-S3 configurations, CONFIG_SPIRAM_MODE_OCT requires pins 33-37 for
PSRAM. So exclude them from the machine_pin_type and machine_pin_irq_type
object tables.
These boards do not build with IDF v4.4 because the section .iram0.text
does not fit in region iram0_0_seg. Enabling SPIRAM increases the code
size so use -Os instead of -O2 to build these boards.
Fixes issue #8260.
Some S2/S3 modules don't use the native USB interface but instead have an
external USB-UART. To make the GENERIC_S3/S3 firmware work on these boards
the UART REPL is enabled in addition to the native USB CDC REPL.
Fixes issues #8418 and #8524.

This reverts commit 7e8222ae06.
The prelude data must exist somewhere in the native code so load_raw_code
and mpy-tool.py can access and parse it.

If MICROPY_SCHEDULER_STATIC_NODES is enabled then C code can declare a
static mp_sched_node_t and schedule a callback using
mp_sched_schedule_node(). In contrast to using mp_sched_schedule(), the
node version will have at most one pending callback outstanding, and will
always be able to schedule if there is nothing already scheduled on this
node. This guarantees that the the callback will be called exactly once
after it is scheduled.

Duplication of characters is caused by re-entrant calls from separate cores
of uart_fill_tx_fifo(). This patch uses a mutex to ensure that a
re-entrant execution of the function returns without affecting the UART
FIFO.
Fixes issues #8344 and #8360.
- Add board-level configuration option to set the SMPS supply mode.
- Wait for valid voltage levels after configuring the SMPS mode.
- Wait for external supply ready flag if SMPS supplies external circuitry.
All user interface (LED, button) code has been moved to ui.c, and the
interface to this code with the rest of the system now goes through calls
to mboot_state_change(). This state-change function can be overridden by a
board to fully customise the user interface behaviour.

The Thumb instruction set has special 16 bit encodings for PUSH involving
LR and POP involving PC, which are commonly used in nested functions.
Using this encoding is particularly important for ARMv6-M, where the more
general 32 bit encoding of PUSH and POP is unavailable.
This follows the CPython change: https://bugs.python.org/issue21455
Socket listen backlog defaults to 2 if not given, based on most bare metal
targets not having many resources for a large backlog. On UNIX it defaults
to SOMAXCONN or 128, whichever is less.
