drm/i915: Kill intel_prepare_ddi()
Move the ddi buffer translation programming to occur from the encoder
.pre_enable() hook, for just the ddi port we are enabling. Previously
we used to reprogram the translations for all ddi ports during
init and during power well enabling.
v2: s/intel_prepare_ddi_buffers/intel_prepare_ddi_buffer/ (Daniel)
Resolve conflicts due to dev_priv->atomic_cdclk_freq
