Generate IPMI Aux firmware revision from VERSION_ID field

IPMI command get device id supports auxiliary firmware version field
in the response. This field is 4 bytes and the first 2 bytes would
contain the count from the version tag in BCD format, the next 2 bytes
would represent the release version in BCD format. This change can
support the VERSION_ID format of IBM enterprise build and a build
from the master.
