drm/i915: Support for Cougarpoint PCH display pipeline
Cougarpoint is the new PCH for Sandybridge CPU. This one resolves the chipset change for display pipeline compared to previous Ibexpeak PCH. Sandybridge/Cougarpoint has different FDI training parameters, so this also makes seperate FDI training functions for IBX and CPT. Other change includes new transcoder DPLL select function to set which DPLL for transcoder to pick up. And with another new transcoder C introduced in Cougarpoint, each connector has new transcoder select bits. This one adds that change to light up VGA.
