This change allows a CPU pin to be hidden from the user by prefixing it
with a "-" in the pins.csv file for a board. It will still be available in
C code, just not exposed to Python.

Don't want users to accidentally use boot.py (because recovering requires
knowing how to activate safe mode).

MCU support for the STM32H7A3 and B3 families MCUs:
- STM32H7A3xx
- STM32H7A3xxQ (SMPS)
- STM32H7B3xx
- STM32H7B3xxQ (SMPS)
Support has been added for the STM32H7B3I_DK board.

To simplify the socket state.
The CC3K driver (see drivers/cc3000/inc/socket.h and src/socket.c) has
socket() returning an INT16 so there is now enough room to store it
directly in the fileno member.
- Moves definition of BOARD_FLASH_SIZE and other header files related to
flash configuration into the Makefile.
- Adds board specific clock_config.h.
- Adds board.h, pin_mux.h, and peripherals.h as they are
required by NXP MCU SDK in order to use our own clock_config.h.
- Renames board specific FlexSPI configuration files.
- Updates flash frequency of MIMXRT1020_EVK
- Creates separated flash_config files for QSPI NOR and
QSPI Hyper flash.
- Unifies VFS start address to be @ 1M for 1010 and 1020 boards.
- Unifies 1050EVK boards
- Adds support to both NOR and HyperFlash on boards with
both capabilities.
- Adds automatic FlexRAM initialization to start-up code based on
linker script and NXP HAL.
- Applies code formatting to all files in mimxrt port.
With this change the flash configuration is restructured and
organized. This simplifies the configuration process and
provides a better overview of each board's settings. With the integration
of clock_config.h, board.h, pin_mux.h, and peripherals.h we gain better
control of the settings and clock configurations. Furthermore the
implementation of an explicit FlexRAM setup improves the system
performance and allows for performance tuning.

Also:
- Use NO_PIN, not 0xff for I2SOut (cosmetic fix only; no actual functional change)
- Add VOLTAGE_MONITOR/BATTERY, ACCELEROMETER_INTERRUPT pins for LED Glasses Driver
It's not possible anymore to build MicroPython on Cygwin using a
standard Windows installation of Python so don't advertise that.
Specifically: preprocessing in makeqstrdefs.py fails on the subprocess
call with 'gcc: fatal error: no input files' because one of the flags
contains double quotes and that somehow messes up the commandline.
Following the code example for ESP32 of Jim Mussard.
As a side effect:
- mp_hal_ticks_cpu() was implemented,
- mp_hal_get_cpu_freq() and mp_hal_ticks_cpu_init() were added and used.
- mp_hal_pin_high() and mp_hal_pin_low() were changed for symmetry
The boot counter is a uint8_t single-byte counter stored in the first NVM byte position (`micrcontroller.nvm[0]`). The counter increments by 1 each time the board boots, regardless if it's a hard or soft reset.
Enable the boot counter by adding `#define CIRCUITPY_BOOT_COUNTER 1` to your board's mpconfigboard.h file. Note that an error will be thrown during the build if `CIRCUITPY_INTERNAL_NVM_SIZE` is not also set within mpconfigboard.h.
The BLE workflow will be advertising and the scan's load of
identities conflicts with it. This change ensures scanning and
advertising happens exclusively.
This showed as an unknown error 3204.
