Subject: [RESEND PATCH] drm/tegra: switch to using devm_fwnode_gpiod_get()

devm_gpiod_get_from_of_node() is going away and GPIO consumers should
use generic device/firmware node APIs to fetch GPIOs assigned to them.
Switch the driver to use devm_fwnode_gpiod_get() instead.

Marked as "resend" since the contents of the patch are the same (however
I did update the description a bit).
