drm/i915: Program DSPCLK_GATE_D only once on Ironlake
With the consolidated registers, it appears that we're setting the same
bis several times. Let's just collect the bits we want to set and program
it once.
v2: More cleanup. Also program 0x42004 and 0x45000 for FBC on non
mobile platforms (Paulo Zanoni)
