[PATCH v2 1/6] drm/sun4i: dsi: Use drm panel_or_bridge call

Right now the driver is finding the panel using of_drm_find_panel,
replace the same with drm_of_find_panel_or_bridge which would help
to find the panel or bridge on the same call if bridge support added
in future.

Added NULL in bridge argument, same will replace with bridge parameter
once bridge supported.
