This may fix cursor corruption in X on resume, which would persist until
the cursor was hidden and then shown again.
V2: Also include the cursor control regs.

This makes software fallbacks not do tiling wrong on i965 and later after
resume. It also should fix 945 performance reduction after resume which
would have disabled tiling without causing any visible effect.

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.
