pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()
In order to introduce a pwm api which can be used from atomic context,
we will need two functions for applying pwm changes:
int pwm_apply_might_sleep(struct pwm *, struct pwm_state *);
int pwm_apply_atomic(struct pwm *, struct pwm_state *);
This commit just deals with renaming pwm_apply_state(), a following
commit will introduce the pwm_apply_atomic() function.
