drm/i915/chv: Pipe select change for DP and HDMI
With additional of pipe C, current 1 bit registers for pipe select
for HDMI and DP are no longer able to gather for 3 pipes. As a result,
new bits location in the same registers are added.
For HDMI, VLV uses bit 30, CHV uses bit 24-25.
For DP, VLV uses bit 30, CHV uses bit 16-17.
