drm/amdgpu: Add UALink NPA address layout helpers

Browse source

Add accessors for the local accelerator ID, addressing mode, and active
peer bitmap, plus a TLB flush helper for the NPA VM. Provide per-ring
size and byte offset helpers for both source-identification and
source-alias addressing modes.
