This is a breaking change, making the hardware PWM on the nrf port
compatible with the other ports providing machine.PWM.
Frequency range 4Hz - ~5.4 MHz. The base clock range is 125kHz to 16 MHz,
and the divider range is 3 - 32767.
The hardware supports up to four outputs per PWM device with different duty
cycles, but only one output is (and was) supported.
So that it doesn't clash with the extmod version.
Also make the default for this enabled, so that most boards do not need to
configure it.

This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.
Optionally supports a board.md for additional customisation of the
download page, as well as deploy.md for flashing instructions.

The "random" module no longer uses the hardware RNG (the extmod version of
this module has a pseudo-random number generator), so the config option
MICROPY_PY_RANDOM_HW_RNG is no longer meaningful. This commit replaces it
with MICROPY_HW_ENABLE_RNG, which controls whether the hardware RNG is
included in the build.
