drm/radeon: clean up vram/gtt location handling
Add a per-asic MC (memory controller) mask which holds the mak address mask the asic is capable of. Use this when calculating the vram and gtt locations rather using asic specific functions or limiting everything to 32 bits. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
