Replace the manual panel handling with usage of the DRM panel bridge helper. This simplifies the driver, and brings support for DRM_BRIDGE_ATTACH_NO_CONNECTOR as an added bonus.

Thanks for your patch, which is now commit e9e056949c927e5b ("drm: rcar-du: lvds: Convert to DRM panel bridge helper") in drm-next.
This causes the following scary messages in the kernel log on Ebisu-4D:
[drm:drm_bridge_attach] *ERROR* failed to attach bridge
Reverting this commit fixes the issue.
Oops, that's not true (should not write tentative messages while booting a test kernel, and press send without checking first ;-)
Reverting the commit doesn't seem to make a difference. But the parent 5bcc48395b9f35da ("drm: bridge: dw-hdmi: Attach to next bridge if available") of the bad commit is fine.
Thanks for the report. I've reproduced this and will send a fix shortly.
