These save & restore functions inside i915_suspend are old display
functions to save and restore a bunch of display related registers.
Move it under display and rename accordantly. Just don't move it
entirely towards intel_display struct yet because it depends
on drm_i915_private for the IS_MOBILE.
While doing this conversion also update the MIT header using
the new SPDX ones.
v2: Fix Makefile and include (Jani)
Removed vga and gmbus (Jani, Ville)
