backlight: lp8788: 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.
