[PATCH v5 16/24] ARM: explicitly apply PWM config extracted from pwm_args

Call pwm_apply_args() just after requesting the PWM device so that the
polarity and period are initialized according to the information provided
in pwm_args.

This is an intermediate state, and pwm_apply_args() should be dropped as
soon as the atomic PWM infrastructure is in place and the driver makes
use of it.
