Prerequisite for enabling Link Time Optimisation.
The _bl_state address is the same as _estack, but _estack is referred to as
a uint32_t elsewhere in the code. LTO doesn't like it when the same symbol
has two different types.

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.

Also make default board behaviour functions always available, named as

- 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.
This is enabled at MICROPY_CONFIG_ROM_LEVEL_EXTRA_FEATURES, which is the
default for stm32. Not setting the value in mpconfigboard.h allows boards
to optionally configure it.

The default stm32lib remains lib/stm32lib, but it can now be easily

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.
The current ST HAL does not support reading the extended CSD so cannot
correctly detect the capacity of high-capacity cards. As a workaround, the
capacity can be forced via the MICROPY_HW_MMCARD_LOG_BLOCK_NBR config
option.

Quail (https://www.mikroe.com/quail, PID: MIKROE-1793) is based on an
STM32F427VI CPU, featuring 2048 kB of Flash memory and 192 kB of RAM. An
on-board Cypress S25FL164K adds 8 MB of SPI Flash.
Quail has 4 mikroBUS(TM) sockets for Mikroe click(TM) board connectivity,
along with 24 screw terminals for connecting additional electronics and two
USB ports (one for programming, the other for external mass storage).
4 UARTs, 2 SPIs and 1 I2C bus are available for communication.

This change adds the OLIMEX H407 support to the STM32 port. The H407
(https://www.olimex.com/Products/ARM/ST/STM32-H407/) is simliar to the
already existing E407
(https://www.olimex.com/Products/ARM/ST/STM32-E407) but does not support
Ethernet and has a full-size USB-A port instead of a Mini-USB socket.
Both boards use the STM32F407ZGT6 CPU.
This port is basically a copy of the E407 but with changed pinmux:
* Removed Ethernet pin definition
* Removed UART1 (pins are used for other functions)
* Removed UART3 flow control pins (pins are used for other functions)
* Removed SD-Card detect pin (since it is not connected on the H407)
A REPL on UART3 is connected to the U3BOOT-header, a 3-pin header with RX,
TX and GND that is intended for the serial terminal.
Tested:
* Micro-SD Card is detected when inserted on RESET
* REPL on UART3 works
* Serial port on the mini USB socket

This commit creates a new stm32 board for the NUCLEO_H743ZI2, which is the
current version of this from ST. This is a modified copy of the
NUCLEO_H743ZI board, and the ZI2 board differs in a few minor ways:
- LED2 has moved from PB7 to PE1 and is now yellow rather than blue
- the USB power enable has moved from PG6 to PG10
- the USER button is now pulled down
Add basic support for LEGO HUB NO.6 (e.g. LEGO SPIKE Prime, LEGO MINDSTORMS
Robot Inventor).
See README.md for details.
Thanks to @dpgeorge for helping put this together.

The ADC_FIRST_GPIO_CHANNEL and ADC_LAST_GPIO_CHANNEL macros are no longer
needed. Instead the pin_adcX table (X = 1, 2, 3) is now generated to be
the exact size needed for a given MCU, and MP_ARRAY_SIZE(pin_adcX) is used
to determine the upper bound.
This commit also allows CPU pins to be excluded from ADC configuration if
they are hidden by prefixing their name with a "-".

Add LPUART1 as a standard UART. No low power features are supported, yet.
LPUART1 is enabled as the next available UART after the standard U(S)ARTs:
STM32WB: LPUART1 = UART(2)
STM32L0: LPUART1 = UART(6)
STM32L4: LPUART1 = UART(6)
STM32H7: LPUART1 = UART(9)
On all ports: LPUART1 = machine.UART('LP1')
LPUART1 is enabled by defining MICROPY_HW_LPUART1_TX and
MICROPY_HW_LPUART1_RX in mpconfigboard.h.
