The VGA registers just hit the pipe registers that we already set through
MMIO. This fixes strange colors on resume.

It fixes suspend/resume failure of xf86-video-intel dri2
branch. As dri2 branch doesn't call I830DRIResume() to restore
hardware status page anymore, we need to preserve
this register across suspend/resume.

This register is set by the 2D driver to prevent lockups, and so it needs to
be preserved across suspend/resume too. This makes my X200s work.

[Patch against drm-next. Consider this a trial balloon for our new Linux
development model.]
This is a big chunk of code. Separating it out makes it easier to change
without churn on the main i915_drv.c file (and there will be churn as we
fix bugs and add things like kernel mode setting). Also makes it easier
to share this file with BSD.
