drm/i915: Do not put big intel_crtc_state on the stack

Browse Source 
Having this on stack triggers the -Wframe-larger-than=1024 and
is not nice to put such big things on the kernel stack anyway.

This required a little bit of refactoring to handle the new
failure path from vlv_force_pll_on.

v2: Corrected some whitespace.
