zephyr: pwm: de-shim the fan driver PWM APIs
Refactor the fan driver to drop the shimmed PWM code and use the Zephyr
PWM APIs directly. Drop the corresponding dts entries, leaving few
pwm.dts files empty, will clear those at a later stage.
BRANCH=none
BUG=b:217741090
TEST=zmake testall
TEST=build and run on volteer, play with faninfo and fanset
