Poulsbo needs a physical address in the cursor base register. We allocate a
stolen memory buffer and copy the cursor image provided by userspace into it.
When/If we get our own userspace driver we can map this stolen memory directly.
The patch also adds a mark in chip ops so we can identify devices that has this
requirement.

We don't need to check these - they are always going to be the
same for any PVR based device.

All the conditional ugly register selection really wants to be
cleaned up. Use a struct describing each pipe and its registers.
This will also let us hide some of the oddments between platforms
for any future merging of bits together. In particular the way the
DPLL and FP registers randomly wander around.

This starts the move away from lots of confused unions of per driver stuff
inherited when we merged the drivers together.

Add the opregion support and bring us in line with the opregion functionality in the
reference driver code. We can't share this with i915 currently because there are
hardcoded assumptions about dev_priv etc in both versions.

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 Oaktrail platform does not use the GCT/VBT format that is used by the
Moorestowm (non PC legacy) equivalent device. It uses the BIOS tables which
means an opregion and the like.
The current code uses the wrong table which breaks things like the Fujitsu
q550 tablets. Fix the table usage as a first step.

Oaktrail (GMA600) is found on some tablet/slate PC type systems. It's a bit
different to the GMA500 but similar enough it makes sense to plug it into
the same driver.
