Chris Wilson f6e5b1603b drm/i915: Sanitize the output registers after resume
Similar to booting, we need to inspect the state left by the BIOS and
remove any conflicting bits before we take over. The example reported by
Seth Forshee is very similar to the bug we encountered with the state left
by grub2, that the crtc pipe<->planning mapping was reversed from our
expectations and so we failed to turn off the outputs when booting or,
in this case, resuming. This may be in fact the same bug, but triggered
at resume time.

This patch rearranges the code we already have to clear up the
conflicting state upon init and calls it from reset (which is called
after we have lost control of the hardware, i.e. along both the boot and
resume paths) instead.
