video: tegra: dc: Correct GPIO definitions

Browse Source 
In Linux v6.12, commit 8c045ca534d0 ("gpiolib: legacy: Kill GPIOF_DIR_*
definitions") removed the GPIOF_DIR_* definitions and updated drivers to
use the equivalent GPIOF_* definitions instead. The GPIOF_* definitions
were added in Linux v3.0 and so update the appropriate drivers to use
these definitions.

Note that when calling devm_gpio_request_one() with GPIOF_DIR_OUT for
the flags, then because no explicit output level is specified, the GPIO
driver core defaults to low. Hence, in this case we replace
GPIOF_DIR_OUT with GPIOF_OUT_INIT_LOW.
