drm/i915/display: Refactor DPKGC code to call it from atomic_commit_tail

Browse Source 
Refactor the code to check the fixed refresh rate condition in the dpkgc
function itself and call it from intel_atomic_commit_tail so that we
have all the required values specially linetime which is computed after
intel_wm_compute, this will also help implement some WA's which requires
linetime. This also avoid writing into any of the registers while we are
in compute_config phase.
