Subject: [PATCH] pwm: Fix kerneldoc for apply operation

As the @state passed to apply() is now const the comment in the
kerneldoc about drivers being expected to adjust the parameters is no
longer valid. Update it to reflect the API change.

Fixes: 71523d1812ac ("pwm: Ensure pwm_apply_state() doesn't modify the state argument")
