drm/amdgpu: fix visible VRAM handling during faults

Browse source

When we removed the hacky start code check we actually didn't took into
account that *all* VRAM pages needs to be CPU accessible.

Clean up the code and unify the handling into a single helper which
checks if the whole resource is CPU accessible.

The only place where a partial check would make sense is during
eviction, but that is neglitible.
