backlight: pwm_bl: add configurable delay between re-enabling PWM and switching backlight power on

When switching the backlight on, the LCD may need some time to adjust
to the configured PWM duty cycle. Add a configurable delay between
configuring the PWM and enabling the backlight regulator to account
for this.
