drm/mediatek: Fix DPI component detection for MT8192

[ Upstream commit cfab37ff31afcd0f99f3cccbff1f8ffa11e44c00 ]

When support for MT8192 was added, the DPI device was not added to the
list of components to look for. This causes the secondary display
pipeline to not be able to fully bind, and the DRM driver subsequently
defers probing.

Add the DPI device compatible to list of DPI components to fix this.
