Damien George 90023b4dcf extmod/modmachine: Clean up decls of machine types to use common ones.
The machine_i2c_type, machine_spi_type and machine_timer_type symbols are
already declared in extmod/modmachine.h and should not be declared anywhere
else.

Also move declarations of machine_pin_type and machine_rtc_type to the
common header in extmod.

Damien George 5b4a2baff6 extmod/machine_uart: Factor ports' UART Python bindings to common code.
This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings.  For all ports except the two listed
below there is no functional change.

The nrf port has UART.sendbreak() removed, but this method previously did
nothing.

The zephyr port has the following methods added:
- UART.init(): supports setting timeout and timeout_char.
- UART.deinit(): does nothing, just returns None.
- UART.flush(): raises OSError(EINVAL) because it's not implemented.
- UART.any() and UART.txdone(): raise NotImplementedError.

Damien George 7e7af71527 extmod/machine_pwm: Remove header file and move decls to .c file.
With public declarations moved to extmod/modmachine.h.  It's now mandatory
for a port to define MICROPY_PY_MACHINE_PWM_INCLUDEFILE if it enables
MICROPY_PY_MACHINE_PWM.  This follows how extmod/machine_wdt.c works.

All ports have been updated to work with this modified scheme.

Damien George 60929ec7e2 extmod/machine_wdt: Factor ports' WDT Python bindings to common code.
There are currently 7 ports that implement machine.WDT and a lot of code is
duplicated across these implementations.  This commit factors the common
parts of all these implementations to a single location in
extmod/machine_wdt.c.  This common code provides the top-level Python
bindings (class and method wrappers), and then each port implements the
back end specific to that port.

With this refactor the ports remain functionally the same except for:

- The esp8266 WDT constructor now takes keyword arguments, and accepts the
  "timeout" argument but raises an exception if it's not the default value
  (this port doesn't support changing the timeout).

- The mimxrt and samd ports now interpret the argument to WDT.timeout_ms()
  as signed and if it's negative truncate it to the minimum timeout (rather
  than it being unsigned and a negative value truncating to the maximum
  timeout).

Jim Mussared 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.

Jim Mussared 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.

repr(uart) shows the pin names for rts and cts, if set.  In case of a RX
overflow, the rx interrupt will be disabled instead of just discarding the
data.  That allows RTS to act.

If RTS is inactive, still 2 bytes can be buffered in the FIFO.
