On i.MX8MQ, the new revision SoC does NOT update the
revision info in ANATOP_DIGPROG register, to support
dynamic SOC id/revision detection, only reading info
from ANATOP_DIGPROG is not working now, change to read
SOC id/revision from ATF which is in secure world.
The ATF will read the ANATOP_DIGPROG as well as ROM
version to decide the SOC revision.
