[PATCH] drm: rcar-du: fix probe error when DRM_RCAR_DW_HDMI disabled

[Nguyen An Hoan]

From: Hoan Nguyen An <na-h...@jinso.co.jp>

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.
