In particular clean up the errata handling and correct the crtc masks. We do
this a bit differently using our device abstraction for neatness.

This doesn't address the ACPI opregion and hotplug plumbing, nor the IRQ related
changes that will need. It touches on backlight init but the full backlight
support is not in this change set.

The problem in console mode is lack of linear memory. We can solve that by
dropping to 16bpp. The mode setting X server will allocate its own GEM
framebuffer in 32bpp and all will be well.

We could just do 16bpp anyway but that would be a regression on the lower
modes as many distributions don't yet ship the generic mode setting KMS
drivers.

Requiring the first byte of the EDID base block header to be 0 means we
don't fix up as many transfer errors as we could.  Instead have the
callers specify whether it's meant to be block 0 or not, and
conditionally run header fixup based on that.

will look for exactly the r-b-ness mentioned in the mode code.  This
