[PATCH 2/9] drm/i915: Use cpu_transcoder for HSW_TVIDEO_DIP_* instead of pipe

[Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx>]

While old platforms had 3 transcoders and 3 pipes (1:1), HSW has 4 transcoders and 3 pipes. To avoid future mistakes transcoders must be used here instead of pipes even though it is working right now by coincidence.
