drm/panel: ld9040: Update calls to gpiod_get*()

Add the new flags argument to calls of (devm_)gpiod_get*() and remove
any direction setting code afterwards.

Currently both forms (with or without the flags argument) are valid
thanks to transitional macros in <linux/gpio/consumer.h>. These macros
will be removed once all consumers are updated and the flags argument
will become compulsary.
