drm/amdgpu: add amdgpu_discovery_get_mem_reserved_region_by_id

Browse source

Add a lookup helper to pass a MEM_RESERVED_REGION_ID and receive the
region's start address and size.

A static amdgpu_discovery_mem_reserved_region_name() helper is also
introduced so debug output can refer to regions by symbolic name rather
than raw IDs.
