drm: Add support for pps and compression mode command packet
After enabling DSC we need to send compression mode command packet
and pps data packet, for which 2 new data types are added
07h Compression Mode Data Type Write , short write, 2 parameters
0Ah PPS Long Write (word count determines number of bytes)
This patch adds support to send these packets.
