Subject: [PATCH 2903/2940] drm/amdgpu: specify sdma instance 5~7 with second
mmhub type
On Arcturus, sdma instance 5~7 is connected to the second mmhub. The vmhub type
in amdgpu_ring_funcs is constant, so we create an individual amdgpu_ring_funcs
with different vmhub type(AMDGPU_MMHUB_1) for these sdma instances.
