cause:
It is necessary to send ras disable command to ras-ta during gfx
block ras later init, because the ras capability is disable read
from vbios for vega20 gaming, but the ras context is released
during ras init process, this will cause send ras disable command
to ras-to failed.
how:
Delay releasing ras context, the ras context
will be released after gfx block later init done.
Changed from V1:
move release_ras_context into ras_resume
Changed from V2:
check BIT(UMC) is more reasonable before access eeprom table
