pwm: Changes for v5.20-rc1

After v5.19 had all drivers converted to the new atomic API and nobody
has reported any breakage, this set of changes starts by dropping the
legacy support.

Some existing drivers get improvements and broader chip support and a
new driver is added that emulates a PWM controller using a clock output.

Other than that there's the usual bits of cleanups and minor fixes.
