Since all boards are configured to have a I2C(0), SPI(0) and UART(1), these
can be set as default devices, allowing the instantiation of I2C(), SPI(),
UART() without an id argument.

This is a board based on the i.MX RT1011 in breadboard-friendly shape. A
good basic board with 16M flash and regular pinout, providing access to
many GPIO_nn and GPIO_AD_nn Pins.

Such that it matches the implementation and the documentation of the
`machine.RTC` class.

The following ports used 65536 as the upper value (100% duty cycle) and are
changed in this commit to use 65535: esp8266, mimxrt, nrf, samd.
Tested that output is high at `duty_u16(65535)` and low at `duty_u16(0)`.
Also verified that at `duty_u16(32768)` the high and low pulse have the
same length.
Partially reverts #10850, commits 9c7ad68165bcd224c94ca6d8f172362cf8000d99
and 2ac643c15bec8c88ece0e944ce58f36d02dfd2dd.

Telling that subseconds is not supported and returns always 0. This was
changed in 913f9ad5ad9bb446c6e4310b6b5eda310098a1cf.

Prune trailing whitespace across the whole project (almost), done
automatically with:
grep -IUrl --color "[[:blank:]]$" --exclude-dir=.git --exclude=*.exp |\
xargs sed -i 's/[[:space:]]*$//'
Exceptions:
- Skip third-party code in lib/ and drivers/cc3100/
- Skip generated code in bluetooth_init_cc2564C_1.5.c
- Preserve command output whitespace in docs, eg:
docs/esp8266/tutorial/repl.rst

Olimex asked for that, getting a UART at the UEXT1 connector as well.

This adds the freq and duty_u16 keyword settings to the constructor, and
sometimes other details in the PWM section.
For mimxrt a clarification regarding the PWM invert argument was added, and
for rp2 a few words were spent on PWM output pairs of a channel/slice.

This releases the hardware timers for other tasks, which need a higher
resolution and faster response. And it is less port-specific code.

In that case, no Pin will be configured for the CS signal, even if it is
internally still generated. That setting allows to use any pin for CS,
which then must be controlled by the Python script.
Also make the default cs=-1 to match other ports (software CS).

This shortens the quickref. Also change the note about the hardware SPI
frequeny limits.
