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

[Alexandre Courbot]

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.

It needs patch "gpio: Fix gpio direction flags not getting set" to work
correctly. It is not yet present in drm-next. Beside this:
