This patch defines TRANS_CONF registers for DSI ports
0 and 1. Bitfields of these registers used for enabling
and reading the current state of transcoder.

v2: Add blank line before comment

v3 by Jani:
  - Move DSI specific .pipe_offsets to GEN11_FEATURES
  - Macro placement and comment juggling

Changes looks ok.

Regards,
Madhav
