Move DisplayPort, HDMI and various other display helpers from KMS
helpers into a new module. Adapt all drivers.

This patch is part of an on-going effort to reduce the minimum size
of DRM when linked into the kernel binary. The helpers for various
display and video-output standards are not required for minimal
graphics output and can be moved into a separate module.

The DisplayPort code was already part of the DP module, which now
forms the base of the display-helper module. Moving other helpers
into the new module reduces KMS helpers by ~14 KiB (from 243 KiB to
229 KiB). More importantly, restructuring the code allows for a more
fine-grained selection of helpers and dependencies.

Built on x86-64, i586, aarch64, and arm.

v2:
	* reduce number of HDMI helpers (Jani)
	* make individual helpers selectable via Kconfig
	* fix several include statements
	* minor cleanups

Thomas Zimmermann (8):
