9573d31071 all: Remove query-variants make target.
This is difficult to implement on cmake-based ports, and having the list
of variants in mpconfigboard.{cmake,mk} duplicates information that's
already in board.json.

This removes the existing query-variants make target from stm32 & rp2
and the definition of BOARD_VARIANTS from the various board files.

Also renames the cmake variable to MICROPY_BOARD_VARIANT to match other
variables such as MICROPY_BOARD. The make variable stays as
BOARD_VARIANT.

24a6e951ec ports: Simplify board feature tags in board.json.
This commit:
- Finds a common set of board feature tags and maps existing features to
  that reduced set.
- Removes some less-useful board feature tags.
- Ensures all MCUs are specified correctly.
- Ensures all boards have a vendor (and fixes some vendor names).

This is to make the downloads page show a less intimidating set of filters.

Work done in conjunction with Matt Trentini <matt.trentini@gmail.com>.

909fe30dfd samd: Set the LFS type in mpconfigmcu.mk instead of mpconfigboard.mk.
SAMD21: set the filesystem type to LFS1.

SAMD51: the type is already set to LFS2, support is now dropped for LFS1.
It has not been used and dropping it saves 10 k of flash.

2b5a5a0f35 samd/samd_qspiflash: Add QSPI flash driver and configure it accordingly.
The QSPI driver provides the interface for using an on-board QSPI flash for
the filesystem.  It provides the same methods as the driver for the
internal flash and uses the same name.  Therefore, only one of the drivers
for internal flash, SPI flash and QSPI flash must be enabled at a time.

315eb949da samd: Rearrange the MCU-specific loader files.
Such that they are easier to adapt.  The maximum code size is set by:

    MICROPY_HW_CODESIZE=xxxK

in mpconfigmcu.mk for the MCU family as default or in mpconfigboard.mk for
a specific board.  Setting the maximum code size allows the loader to error
out if the code gets larger than the space dedicated for it.

Remove two SPARKFUN_SAMD51_THINGS_PLUS pin definitions.  There were
definitions of TXD and RXD, but these pins do not exist on the board.  They
were only shown in the schematics.

Also remove any reference to LED_.  This is just a text change, no

    0  INTREF  internal bandgap reference
    1  INTVCC1 Analog voltage supply
    2  INTVCC0 1/2 Analog voltage supply (only for VDDANA > 2.0v)
    3  AREFA   External reference A
    4  AREFB   External reference B
    5  AREFC   External reference C (ADC1 only)

DAC: The argument of vref=num is an integer. Suitable values:

    SAMD21:
    0  INT1V   Internal voltage reference
    1  VDDANA  Analog voltage supply
    2  VREFA   External reference

    SAMD51:
    0  INTREF Internal bandgap reference

e5cf3fab95 samd/machine_pin: Change the pin handling and naming/numbering.
Pin numbers are now the MCU port numbers in the range:

    PA0..PA31:  0..31
    PB0..PB31: 32..63
    PC0..PC31: 64..95
    PD0..PD31: 96..127

Pins can be denoted by the GPIO port number, the name as defined in
pins.csv or a string in the form Pxnn, like "PA16" or "PD03".

The pins.c and pins.h files are now obsolete.  The pin objects are part of
the AF table.

As result of a simplification, the code now supports using pin names or
numbers instead of pin objects for modules like UART, SPI, PWM, I2C, ADC,
pininfo.

20e7313453 samd/clock_config: Add HW_DFLL_USB_SYNC and HW_MCU_OSC32KULP extensions.
Two new compile flags are:

MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal.  It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode.  The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.

MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source.  Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal.  This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash.  Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.
