Prior to this fix, if the ADC atten value was not explicitly given then
adc1_config_channel_atten() would never be called.
Fixes issue #8275.

Changes are:
- decision to remount local filesystem on remote device is made only if
"MPY: soft reboot" is seen in the output after sending a ctrl-D
- a nice message is printed to the user when the remount occurs
- soft reset during raw REPL is now handled correctly
Fixes issue #7731.

A backslash in the directory name will end up being passed through to the
device and becoming a backslash in a filename, rather than being
interpreted as directories. This makes "cp -r" problematic on Windows.
Changing to simply "/",join() fixes this.
The correct day-of-week is stored in the RTC (0=Monday, 6=Sunday) so there
is no need to adjust it for the return value of time.localtime().
Fixes issue #7889.

The default stm32lib remains lib/stm32lib, but it can now be easily
overriden at build time by specifying STM32LIB_DIR, or STM32LIB_CMSIS_DIR
and STM32LIB_HAL_DIR.

This also fixes a possible race condition when exiting initialisation mode:
reading then writing to ISR (via ISR &= ~RTC_ISR_INIT) will clear any flags
that were set by the hardware between the read and the write. The correct
way to clear just the INIT bit is to just do a single write via ISR =
~RTC_ISR_INIT, which will not clear any other flags (they must be written
to 0 to clear), and that is exactly what LL_RTC_DisableInitMode does.

And don't assert on the sector number in sector_erase, so it can support
erasing arbitrary sectors.

The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c. Enabling MICROPY_PY_MACHINE will include this
module.
As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

This change allows the same heap allocation rules to be used when using
malloc regardless if the board has SPRAM or normal RAM.
Integrating with the esp32-camera for example requires that ESP32 SPRAM be
allocatable using the esp-idf capabilities aware allocation functions. In
the case of esp32-camera it's for the framebuffer.
Detect when CONFIG_SPIRAM_USE_MALLOC is in use and use the standard
automatic configuration of leaving 1/2 of the SPRAM available to other
FreeRTOS tasks.
For example the ESP32-C3 has 2 TX channels and 2 RX channels in total, and
in this case channel 1 must be the default for bitstream.

This commit adds support for the STM32G4 series of MCUs, and a board
definition for NUCLEO_G474RE. This board has the REPL on LPUART1 which is
connected to the on-board ST-link USB-UART.
It's needed at least on F4 because this file overrides the weak function
HAL_RCC_DeInit() from hal_rcc.c.

PLL3-Q is more reliable than PLL1-Q for the USB clock source when entering
mboot from various reset states (eg power on vs MCU reset). (It was found
that if the main application used PLL3-Q then sometimes the USB clock
source would stay stuck on PLL3-Q and not switch to PLL1-Q after a reset.)
Other related changes:
- SystemCoreClockUpdate() should be called on H7 because the calculation
can be involved in some cases.
- __set_PRIMASK(0) should be called because on H7 the built-in ST DFU
bootloader exits with IRQs disabled.

H7 MCUs have ECC and writes do not go through to SRAM until 64-bits have
been written (on another location is written). So use 64-bit writes for
the bootloader-state variable so it is committed before the system reset.
As part of this change, the lower byte of the bootloader address in
BL_STATE must now be the magic number 0x5a5 for the state to be valid
(previously this was 0x000 which is not as robust).
