drm/amdgpu: fix AGP addressing when GART is not at 0
This worked by luck if the GART aperture ended up at 0. When
we ended up moving GART on some chips, the GART aperture ended
up offsetting the AGP address since the resource->start is
a GART offset, not an MC address. Fix this by moving the AGP
address setup into amdgpu_bo_gpu_offset_no_check().
v2: check mem_type before checking agp
v3: check if the ttm bo has a ttm_tt allocated yet
