  AMDGPU: Add and clarify reserved address spaces (#166486)

Address spaces 10 and 11 are reserved for future use in the sense that
we plain to upstream their use.

Address space 12 is used by LLPC. It is used in a workaround for an
issue with SMEM accesses to PRT buffers that is specific to the LLPC
ecosystem and makes no sense to upstream.
