allow legacy handlers to register with groupoem extension

DCMI uses the group oem extension 0xdc. The legacy registration
allowed for registering with the group extension netfn and did nothing
with the actual group extension ID. This change makes the assumption
that all legacy group extension registrations are dcmi and registers
them as such with the new group handler machinery.

Tested-by: Run ipmitool dcmi discover and see it show information
