From: Hoan Nguyen An <na-hoan@xxxxxxxxxxx>
Skip return EPROBE_DEFER when DRM_RCAR_DW_HDMI is disabled in case HDMI initialize.
At this time, the rcar-du driver not be able to successfully initialize
if disable DRM_RCAR_DW_HDMI (rcar_du_probe return error),
so can not use other features such as RGB Analog, this patch to fix.
