drm/radeon: clean up active vram sizing
If we are not able to properly initialize one of the gpu engines for buffer paging, we limit vram to the size of the cpu visible aperture. We generally either use the gfx or dma engine to do this. Clean up the size limiting code to only adjust the size based on what ring is selected for buffer paging rather than making assumptions about which engine is selected for paging.
