This converts the Rockchip RK3288 HDMI driver to use GPIO descriptors:
- Look up the HP EN GPIO as an optional descriptor and handle it directly, the gpiod API is NULL-tolerant so no special guards are needed.
- Let the Jack detection core obtain and handle the HP detection GPIO, just pass the right name and gpiod_dev and it will do the job. Make sure to check that the GPIO property is there first, so it becomes optional.
