[PATCH 2/7] drm/i915: Rename intel_shared_dpll_commit() to _swap_state()

[Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com>]

The function intel_shared_dpll_commit() performs the equivalent of
drm_atomic_helper_swap_state() for the shared dpll state, which is not
handled by the helpers. So make it do a full swap of the state and
rename it for consistency.

v2: Fix typo in the commit message. (Durga)
v3: Rebase.
v4: Swap the states instead of just renaming the function. (Daniel)
