Alexander Lam 18b2190ca5 drm/i915: allow 945 to control self refresh (CxSR) automatically 
I changed 945's self refresh to work without the need for the driver to
enable/disable self refresh manually based on the idle state of the gpu.
This is much better than enabling/disabling self refresh for various
reasons, including staying in a lower power state for more time and
avoiding the need for cpu cycles.

This was originally done manually to workaround issues with the hardware
hanging. However, since 944001201: drm/i915: enable low power render
writes on GEN3 hardware, automatic CxSR seems stable.

[ickle: play safe with the ordering and disable CxSR before tweaking any
watermark and enable afterwards.]
