pwm: Changes for v5.14-rc1

This contains mostly various fixes, cleanups and some conversions to the
atomic API. One noteworthy change is that PWM consumers can now pass a
hint to the PWM core about the PWM usage, enabling PWM providers to
implement various optimizations.

There's also a fair bit of simplification here with the addition of some
device-managed helpers as well as unification between the DT and ACPI
firmware interfaces.
