drm/i915: Fix up cpt pixel multiplier enable sequence
Bspec for the "DPLL HDMI multiplier" field says:
"Restriction : The DPLL must be enabled and stable before setting these bits.
These bits must be programmed after DPLL_SEL is programmed."
There is apparently no restriction on programming the DPLL_SEL
register wrt the DPLL. So let's just move that up before we enable the
pch dpll.
