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.
