drm/amd/display: parse umc_info or vram_info based on ASIC

[ Upstream commit 2551b4a321a68134360b860113dd460133e856e5 ]

An upstream bug report suggests that there are production dGPUs that are
older than DCN401 but still have a umc_info in VBIOS tables with the
same version as expected for a DCN401 product. Hence, reading this
tables should be guarded with a version check.
