Philip Yang ec3db8a63d drm/amdgpu: enable paging queue doorbell support v4
Because increase SDMA_DOORBELL_RANGE to add new SDMA doorbell for paging queue will
break SRIOV, instead we can reserve and map two doorbell pages for amdgpu, paging
queues doorbell index use same index as SDMA gfx queues index but on second page.

For Vega20, after we change doorbell layout to increase SDMA doorbell for 8 SDMA RLC
queues later, we could use new doorbell index for paging queue.
