Make XRGB8888 the only driver-emulated legacy format
* fb-helper: Avoid blank consoles from selecting an incorrect color format
* probe-helper: Enable/disable HPD on connectors plus driver updates
* Use drm_dbg_ helpers in several places
* docs: Document defaults for CRTC backgrounds; Document use of drm_minor
Driver Changes:
* arm/hdlcd: Use new debugfs helpers
