oem-ibm: Support for concurrent out-of-band FW update

Redfish triggers the out-of-band code update to BMC. This code update is
called concurrent FW update when the remote PLDM terminus is up during
code update.

The system has two boot sides: Temporary and Permanent, with the default
image running from the temporary side. During an out-of-band (OOB) code
update triggered by the Redfish client, the boot side is swapped, the
correct image is assigned to the permanent side, and a new image is
written to the temporary side. Boot side rename event is used to notify
the remote PLDM terminus about the rename operation during the update.
