backlight: pwm_bl: Simplify usage of devm_gpiod_get_optional 



Since 39b2bbe3 (gpio: add flags argument to gpiod_get*() functions),
the gpiod_get* functions take an additional parameter that allows to
specify direction and initial value for output.
Simplify the usage of devm_gpiod_get_optional accordingly.
