dev-amdgpu: Place all user-mode translations in MMHUB
The memory management hub ("mmhub") is an aperture that aliases the GPU
device memory. MMHUB addresses functionally map to the same device
address, with the exception that it is guaranteed not to overlap with
host memory. This is useful in gem5 for APIs with Addr type as it
prevents sending e.g., DMAs to the wrong place.
