drm/scdc-helper: Pimp SCDC debugs

Include the device and connector information in the SCDC
debugs. Makes it easier to figure out who did what.

drm/scdc: Document hotplug gotchas

There's some interactions between the SCDC setup and the disconnection /
reconnection of displays. Let's document it and a solution.

drm/display: Move SCDC helpers into display-helper library

SCDC is the Status and Control Data Channel for HDMI. Move the SCDC
helpers into display/ and split the header into files for core and
helpers. Update all affected drivers. No functional changes.

To avoid the proliferation of Kconfig options, SCDC is part of DRM's
support for HDMI. If necessary, a new option could make SCDC an
independent feature.
