drm/amdgpu: fix unknown vram mem type for vega20 

vega20 should use umc_info v3_3 instead of v3_1. There are
serveral versions of umc_info for vega series. Compared to
various versions of these structures, vram_info strucure is
unified for vega series. The patch switch to query mem_type
from vram_info structure for all the vega series dGPU.
