drm/i915/ddi: Push pipe clock enabling to encoders
On ICL the pipe clock needs to be enabled before setting the HDMI infoframe, but these steps are in the reverse order atm. Move the pipe clock enabling to the encoders, so reordering of the two steps can be done in a clean way. No functional change. v2: - Rebased on drm-tip.
