drm/i915: Remove the encoder update_prepare()/complete() hooks

Browse source

The encoder update_prepare()/complete() hooks were added to hold a
TC port link reference for all outputs in the atomic state around the
whole modeset enable sequence - thus locking the ports' TC mode - and
set the TBT/DP-alt PLL type corresponding to the current TC mode.

Since nothing depends on the PLL selection before/after then encoder's
pre_pll_enable/post_pll_disable hooks are called, the above steps can be
moved to these hooks, so do that and remove the
update_prepare()/complete() hooks.
