drm/doc: add rfc section for small BAR uapi

2022-07-01T07:29:29Z

Add an entry for the new uapi needed for small BAR on DG2+. v2: - Some spelling fixes and other small tweaks. (Akeem & Thomas) - Rework error capture interactions, including no longer needing NEEDS_CPU_ACCESS for objects marked for capture. (Thomas) - Add probed_cpu_visible_size. (Lionel) v3: - Drop the vma query for now. - Add unallocated_cpu_visible_size as part of the region query. - Improve the docs some more, including documenting the expected behaviour on older kernels, since this came up in some offline discussion. v4: - Various improvements all over. (Tvrtko) v5: - Include newer integrated platforms when applying the non-recoverable context and error capture restriction.
