drm/doc/rfc: i915 DG1 uAPI

Add an entry for the new uAPI needed for DG1. Also add the overall
upstream plan, including some notes for the TTM conversion.

v2(Daniel):
  - include the overall upstreaming plan
  - add a note for mmap, there are differences here for TTM vs i915
  - bunch of other suggestions from Daniel
v3:
 (Daniel)
  - add a note for set/get caching stuff
  - add some more docs for existing query and extensions stuff
  - add an actual code example for regions query
  - bunch of other stuff
 (Jason)
  - uAPI change(!):
- try a simpler design with the placements extension
- rather than have a generic setparam which can cover multiple
  use cases, have each extension be responsible for one thing
  only
v4:
 (Daniel)
  - add some more notes for ttm conversion
  - bunch of other stuff
 (Jason)
  - uAPI change(!):
- drop all the extra rsvd members for the region_query and
  region_info, just keep the bare minimum needed for padding
v5:
(Jason)
  - for the upstream plan, add a requirement that we send the uAPI bits
    again for final sign off before turning it on for real
  - document how we intend to extend the rsvd bits for the region query
(Kenneth)
  - improve the comment for the smem+lmem mmap mode and caching
