drm/i915: Add the support of memory self-refresh on IronlakeHEADencoder-rework
Update the self-refresh watermark for display plane/cursor and enable
the memory self-refresh on Ironlake. The watermark is also updated for
the active display plane.
More than 1W idle power is saved on one Ironlake laptop after enabling
memory self-refresh.
