drm/amdgpu/sriov: Need to initialize the HDP_NONSURFACE_BAStE
[ Upstream commit fe2b5323d2c3cedaa3bf943dc7a0d233c853c914 ]
it requires to initialize HDP_NONSURFACE_BASE, so as to avoid
using the value left by a previous VM under sriov scenario.
v2: it should not hurt baremetal, generalize it for both sriov
and baremetal
