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. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Dan Williams <[email protected]>
