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.

We have lots of local assignments that can now be eliminated

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

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.

We need to merge this ahead of some of the cleanup because a lot of needed
cleanup spans both new and old chips. If we try and clean up and the merge
we end up fighting ourselves.
