isci: Add support for probing OROM for OEM params
We need to scan the OROM for signature and grab the OEM parameters. We
also need to do the same for EFI. If all fails then we resort to user
binary blob, and if that fails then we go to the defaults.
Share the format with the create_fw utility so that all possible sources
of the parameters are in-sync.
