Currently we just print a hardware specific bitmask when
encountering any kind of display fault error. To make these
errors a bit easier to decode (and perhps even analyze)
I now decode the actual bits, and for plane faults provide
a dump of a few (hopefully) relevant plane registers (CTL,
SURF,SURFLIVE for now, which should at least help with faults
cause by bad GTT alignment).

So far we only reported faults on bdw+, but I'm also hooking
this stuff up for all ilk+ and vlv/chv. The older gmch
platforms I left out for now, but I think i965/g4x should
at least be diable in the future.

Not sure I'm 100% satisfied with how the pipe_fault_handler
thing is structured, but at least it works.

v2: Adjust to intel_display changes
    Add the xe gen2_error_regs stuff in the same patch as i915
