This will be used laster when the encoder and transmitters
are set up.

FB read/write really doesn't need to access the actual VRAM, we
can just use a scratch area. This is required for using atom displayport
calls later.

Both radeon and nouveau can re-use this code so move it up a level
so they can. However the hw interfaces for aux ch are different
enough that the code to translate from mode, address, bytes
to actual hw interfaces isn't generic, so move that code into the
Intel driver.

Grab pll ref div from regs at driver init. r4xx seems very
picky about the dividers for the pll driving lvds.

This is intended to be used by ttm-aware drivers to
1) Block clients to inactive masters when
they try to validate buffers for GPU use.
2) Optionally block clients to the current master when
there is thrashing due to GPU memory shortage.
Used by the vmwgfx driver.

Add objects needed for user-space to maintain reference counts on ttm objects.
This is used by the vmwgfx driver which allows user-space to maintain
map-counts on dma buffers, lock-counts on the ttm lock and ref-counts on
gpu surfaces, gpu contexts and dma buffer.

Again we try to put VRAM at 0, and it didn't work on this chipset,
reports of corrupt RAM appeared on irc and bugzilla.
Fix the vram location according to what the BIOS setup, I'm not 100%
sure we don't need the same thing on rs690/rs780/rs880, we probably
should do it there just in case as its what the DDX does.

Set up rs600 gart like r600:
- set gart system aperture to vram
- inside gart system aperture is unmapped*
- outside gart system aperture is mapped*
*mapped refers to memory handled by page tables
