According to mtk_drm_kms_init(), the all_drm_private array in each
drm private data stores all drm private data in display path order.
In mtk_drm_get_all_drm_priv(), each element in all_drm_priv should have one
display path private data, such as:
all_drm_priv[CRTC_MAIN] should only have main_path data
all_drm_priv[CRTC_EXT] should only have ext_path data
all_drm_priv[CRTC_THIRD] should only have third_path data
So we need to add the length checking for each display path before
assigning their drm private data into all_drm_priv array.
Then the all_drm_private array in each drm private data needs to be
assigned in their display path order.
