drm/i915/dmc: Load DMC on MTL

Browse source

Add support to load DMC on MTL.

According to the spec and based on tests done on real hardware, 0x7000
is a reasonable size limit that covers each possible payload.

v2:
  - Tighten payload size limit. (Matt, Rodrigo)
  - Use a better name for the defined payload limit. (Rodrigo)
