drm/amdgpu: Add a new NPA Address space
Add a new address space for NPA address management.
This is needed for sharing buffer objects across GPUs
with each running their own OS. The NPA address space
size can change across different HW generations so the
size is initialized during early init of the driver boot
up process.
