docs: Update the PWM examples based on recent API improvements.
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.
