drm/mediatek: Add crtc path enum for all_drm_priv array

Browse Source 
[ Upstream commit 26c35d1d1646e593e3a82748b19d33b164871ae8 ]

Add mtk_drm_crtc_path enum for each display path.

Instead of using array index of all_drm_priv in mtk_drm_kms_init(),
mtk_drm_crtc_path enum can make code more readable.
