David Lechner fc3d7ae11b py/make_root_pointers: Add MP_REGISTER_ROOT_POINTER parser/generator.
This adds new compile-time infrastructure to parse source code files for
`MP_REGISTER_ROOT_POINTER()` and generates a new `root_pointers.h` header
file containing the collected declarations.  This works the same as the
existing `MP_REGISTER_MODULE()` feature.

Damien George 45a0c6da5b stm32/mboot: Remove MP_WEAK on led funcs and make some of them static.
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.

Damien George c8c229b96c stm32/mboot: Use PLL3 for USB clock source on H7 MCUs.
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.

Damien George ea81bcf1c0 stm32/mboot: Leave bootloader from thread mode, not from IRQ.
Leaving the bootloader from an IRQ (eg USB or I2C IRQ) will not work if
MBOOT_LEAVE_BOOTLOADER_VIA_RESET is disabled, ie if mboot jumps directly to
the application.  This is because the CPU will still be in IRQ state when
the application starts and IRQs of lower priority will be blocked.

Fix this by setting a flag when the bootloader should finish, and exit the
bootloader always from the main (top level) thread.

This also improves the USB behaviour of mboot: it no longer abruptly
disconnects when the manifest command is sent.

Damien George 9a0bca2c2a stm32/mboot: Make LEDs and reset-mode selection more configurable.
A board can now customise mboot with:
- MBOOT_LED1, MBOOT_LED2, MBOOT_LED3, MBOOT_LED4: if it needs to have
  different LEDs for mboot compared to the application
- MBOOT_BOARD_LED_INIT: if it needs a fully customised LED init function
- MBOOT_BOARD_LED_STATE: if it needs a fully customised LED state-setting
  function
- MBOOT_BOARD_GET_RESET_MODE: if it needs a fully customised function to
  get the reset mode

With full customisation, the only requirement is a single LED to show the
status of the bootloader (idle, erasing, flashing, etc), which can be
configured to do nothing if needed.

Damien George 6639e282c7 stm32/mboot: Add MBOOT_LEAVE_BOOTLOADER_VIA_RESET option.
It is enabled by default to get the standard behaviour of doing a reset
after it is finished, but can be disabled by a board to jump straight to
the application (likely the board needs to use MBOOT_BOARD_CLEANUP to make
this work).

The application is passed a reset mode of BOARDCTRL_RESET_MODE_BOOTLOADER
if the bootloader was active and entered via a jump.
