[PATCH v2 04/10] backlight: pwm_bl: remove useless call to pwm_set_period

[Boris Brezillon]

The PWM period will be set when calling pwm_config. Remove this useless
call to pwm_set_period, which might mess up with the initial PWM state
once we have added proper support for PWM init state retrieval.
