drm/i915/icl: Add VIDEO_DIP registers 

The Picture Parameter Set metadata for DSC has to be sent
to the panel through secondary data packets. Add the error
correction registers, data registers and control registers
for the same.

The control registers for  transcoders A and B are already
defined and will be reused for Icelake purpose. This patch adds
Control register for EDP and transcoder C apart from adding the
PPS data and error registers.

v2: reuse MMIO_TRANS2 for _PPS_DATA and _PPS_ECC.
The  _MMIO_TRANS2(pipe, reg) macro definition takes care of the eDp case
