drm/i915/dip: Add new file to handle Data Island Packet hardware

Browse source

Add new files intel_dip.c, intel_dip.h, and intel_dip_regs.h to handle
low level hardware programming related to Data Island Packets.

Currently only programming of the Transmission Line for HDMI 2.1
Extended Metadata Packet (EMP) and DP Adaptive-Sync Secondary Data
Packet (SDP) is added (MMIO register EMP_AS_SDP_TL).

This will serve as a common place for DIP related code, which is currently
scattered across DP and HDMI files. A TODO has been added for extracting
the remaining DIP helpers.
