Lasse Dalegaard 28f60f7ef6 rp2040: hardware PWM support ...

This implements hardware PWM support for the rp2040. The maximum
value(100% duty) is set to 255 to match the other controllers. Cycle
time is clamped automatically, and uses the full 8.4 fractional range of
the rp2040 PWM block. This allows a maximum PWM frequency of 490kHz and
a minimum frequency of 1915 Hz.
