     drm/i915: framebuffer compression for pre-GM45

     This patch adds framebuffer compression (good for about ~0.5W power
     savings in the best case) support for pre-GM45 chips.  GM45+ have a 
new,
     more flexible FBC scheme that will be added in a separate patch.

     FBC can't always be enabled: the compressed buffer must be physically
     contiguous and reside in stolen space.  So if you have a large display
     and a small amount of stolen memory, you may not be able to take
     advantage of FBC.  In some cases, a BIOS setting controls how much
     stolen space is available.  Increasing this to 8 or 16M can help.
