drm/amdgpu: move nbio sdma_doorbell_range() into sdma code for vega
This mirrors what we do for other asics and this way we are sure the sdma doorbell range is properly initialized. There is a comment about the way doorbells on gfx9 work that requires that they are initialized for other IPs before GFX is initialized. However, the statement says that it applies to multimedia as well, but the VCN code currently initializes doorbells after GFX and there are no known issues there. In my testing at least I don't see any problems on SDMA. This is a prerequisite for fixing the Unsupported Request error reported through AER during driver load. Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373 The error was unnoticed before and got visible because of the commit referenced below. This doesn't fix anything in the commit below, rather fixes the issue in amdgpu exposed by the commit. The reference is only to associate this commit with below one so that both go together.
