[Intel-gfx] [PATCH 3/4] drm/i915: Push TRANS_DDI_FUNC_CTL into the encoder->enable() hook

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Push the TRANS_DDI_FUNC_CTL into the encoder enable hook. The disable
is already there, and as a followup will enable us to pass the encoder
all the way down.
