drm/i915: Plumb crtc_state to link training
Get rid of mode crtc->config usage, and some ad-hoc intel_dp state
usage by plumbing the crtc state all the way down to the link training
code.
Unfortunately we do have to keep some cached state in intel_dp so
that we can do the "does the link need retraining?" checks from
the short hpd handler.
v2: Add intel_crtc_state forward declaration
v3: Don't kill the PHY test code totally since it's
now in the hotplug work where we can get at the states
v4: Don't resurrect the debug scrambling disable bit (Imre)
Use intel_dp_mst_is_master_trans() (Imre)
