drm/i915/icl: Define TRANS_CONF register for DSI

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
