drm/i915: Read out display FIFO size on VLV/CHV
VLV/CHV have similar DSPARB registers as older platforms, just more of
them due to more planes. Add a bit of code to read out the current FIFO
split from the registers. Will be useful later when we improve the WM
calculations.
v2: Add display_mmio_offset to DSPARB
