drm/i2c: tda998x: prepare for video input configuration
The video-input-port (VIP) is highly configurable. This prepares
current driver to allow to configure VIP configuration, as some
boards connect lcd controller and TDA998x "pin-swapped" and depend
on VIP to swap the pins by register configuration.
