Subject: [PATCH] drm/mediatek: Fix DPI component detection for MT8192

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.
