Update minimal port to use the new "minimal" rom level config (this is a
no-op change, the binary is the same size and contains the exact same
symbols).

This is the beginning of a set of changes to simplify enabling/disabling
features. The goals are:
- Remove redundancy from mpconfigport.h (never set a value to the default
-- make it clear exactly what's being enabled).
- Improve consistency between ports. All "similar" ports (i.e. approx same
flash size) should get the same features.
- Simplify mpconfigport.h -- just get default/sensible options for the size
of the port.
- Make it easy for defining constrained boards (e.g. STM32F0/L0), they can
just set a lower level.
This commit makes a step towards this and defines the "core" level as the
current default feature set, and a "minimal" level to turn off everything.
And a few placeholder levels are added for where the other ports will
roughly land.
This is a no-op change for all ports.

Any external user of DMA (eg a board with a custom DMA driver) must call
dma_external_acquire() for their DMA controller/stream to ensure that the
DMA clock is not automatically turned off while it's still being used
externally.

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.

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.
The network.STA_IF and network.AP_IF constants are now independent to the
CYW43_ITF_STA and CYW43_ITF_AP constants.

- 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.

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.
This commit simplifies and optimises the parse tree in-memory
representation of lists of expressions, for tuples and lists, and when
tuples are used on the left-hand-side of assignments and within del
statements. This reduces memory usage of the parse tree when such code is
compiled, and also reduces the size of the compiler.
For example, (1,) was previously the following parse tree:
expr_stmt(5) (n=2)
atom_paren(45) (n=1)
testlist_comp(146) (n=2)
int(1)
testlist_comp_3b(149) (n=1)
NULL
NULL
and with this commit is now:
expr_stmt(5) (n=2)
atom_paren(45) (n=1)
testlist_comp(146) (n=1)
int(1)
NULL
Similarly, (1, 2, 3) was previously:
expr_stmt(5) (n=2)
atom_paren(45) (n=1)
testlist_comp(146) (n=2)
int(1)
testlist_comp_3c(150) (n=2)
int(2)
int(3)
NULL
and is now:
expr_stmt(5) (n=2)
atom_paren(45) (n=1)
testlist_comp(146) (n=3)
int(1)
int(2)
int(3)
NULL

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
- Configures `PLL2->PFD0` with **198MHz** as base clock of
`USDHCx` peripheral.
- Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD`
- Adds creation of pin defines for SDCard to make-pins.py
- Adds new configuration option for SDCard peripheral pinout
to mpconfigport.h
- Adds interrupt handling support instead of polling
- Adds support for `ADMA2` powered data transfer
- Configures SDCard to run in HS (high-speed mode) with **50MHz** only!
SDCard support is optional and requires `USDHC` peripheral.
Thus this driver is not available on `MIMXRT1010_EVK`.
SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1`
in mpconfigboard.mk.

This commit refactors machine.PWM and creates extmod/machine_pwm.c. The
esp8266, esp32 and rp2 ports all use this and provide implementations of
the required PWM functionality. This helps to reduce code duplication and
keep the same Python API across ports.
This commit does not make any functional changes.
