pwm: Two fixes for the pwm core and the pwm-microchip-core driver

Conor Dooley found and fixed a problem in the pwm-microchip-core driver
that existed since the driver's birth in v6.5-rc1. It's about a corner
case that only happens if two pwm devices of the same chip are set to
the same long period.

The other problem is about the new pwm API that currently is only
supported by two hardware drivers. The fix prevents a NULL pointer
exception if one of the new functions is called for a pwm device with a
driver that only provides the old callbacks.
