The other patch transforms intel_pch_enable_pll (hmm, that's actually
a better name ;-) into a no-op if the crtc does not require a pll. Which
I think is the easier way of tracking PLLs - allocate on up front if the
chipset/output requires a PLL and then we do no need any more checks
other than has-pll? in the main body of the code.
