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