96c6b8cae3 ports: Rename USBD_VID/PID config macros to MICROPY_HW_USB_VID/PID.
For consistency with other board-level config macros that begin with
MICROPY_HW_USB.

Also allow boards in the mimxrt, nrf and samd ports to configure these
values.

    - blocking
    - non-blocking with callback
    - uasyncio
  - internal ring buffer size can be tuned
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
  - Pyboard D SF2W

The ADC_FIRST_GPIO_CHANNEL and ADC_LAST_GPIO_CHANNEL macros are no longer

the exact size needed for a given MCU, and MP_ARRAY_SIZE(pin_adcX) is used
to determine the upper bound.

they are hidden by prefixing their name with a "-".

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.

a96afae90f stm32/sdio: Fix case of SDIO DMA turning off mid transfer.
The DMA driver will turn off DMA if it hasn't been used for an amount of
time (to save power).  The SDIO driver for cyw43 WLAN was not informing the
DMA driver that it was using DMA and there was a chance that the DMA would
turn off in the middle of an SDIO DMA transfer.  The symptoms of this would
be printing of SDIO error messages and a failure to communicate with the
cyw43 WLAN module.

This commit fixes this issue by changing the SDIO driver to use the
dma_nohal_XXX API to initialise and start the DMA.

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.

647fa63f9c stm32/softtimer: Support static soft timer instances.
This adds support for making static (ie not on the Python GC heap) soft
timers.  This can be useful for a board to define a custom background
handler, or eventually for BLE/network processing to use instead of systick
slots; it will be more efficient using soft timer for this.

The main issue with using the existing code for static soft timers is that
it would combine heap allocated and statically allocated soft_timer_entry_t
instances in the same pairing-heap data structure.  This would prevent the
GC from tracing some of the heap allocated entries (because the GC won't
follow pointers outside the heap).

This commit makes it so that soft timer entries are explicitly marked,
instead of relying on implicit marking by having the root of the pairing
heap in the root pointer section.  Also, on soft reset only the heap-
allocated soft timers are deleted from the pairing heap, leaving the
statically allocated ones.

2668337f36 stm32/rfcore: Intercept addr-resolution HCI cmd to work around BLE bug.
The STM32WB has a problem when address resolution is enabled: under certain
conditions the MCU can get into a state where it draws an additional 10mA
or so and eventually ends up with a broken BLE RX path in the silicon.  A
simple way to reproduce this is to enable address resolution (which is the
default for NimBLE) and start the device advertising.  If there is enough
BLE activity in the vicinity then the device will at some point enter the
bad state and, if left long enough, will have permanent BLE RX damage.

STMicroelectronics are aware of this issue.  The only known workaround at
this stage is to not enable address resolution, which is implemented by
this commit.

Work done in collaboration with Jim Mussared aka @jimmo.

dd62c52a36 stm32/rfcore: Fix race condition with C2 accessing free buffer list.
Prior to this commit, if C2 was busy (eg lots of BLE activity) then it may
not have had time to respond to the notification on the IPCC_CH_MM channel
by the time additional memory was available to put on that buffer.  In such
a case C1 would modify the free buffer list while C2 was potentially
accessing it, and this would eventually lead to lost memory buffers (or a
corrupt linked list).  If all buffers become lost then ACL packets
(asynchronous events) can no longer be delivered from C2 to C1.

This commit fixes this issue by waiting for C2 to indicate that it has
finished using the free buffer list.

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.
