drm/mediatek: Add connector dynamic selection capability
Add dynamic select available connector flow in mtk_drm_crtc_create()
and mtk_drm_crtc_atomic_enable().
In mtk_drm_crtc_create(), if there is a connector routes array in drm
driver data, all components definded in the connector routes array will
be checked and their encoder_index will be set.
In mtk_drm_crtc_atomic_enable(), crtc will check its encoder_index to
identify which componet in the connector routes array should append.
