Dan Williams d044af17aa 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.

This defines the temporary binary blow we are to pass to the SCU
driver to emulate the binary firmware that we will eventually be
able to access via NVRAM on the SCU controller.

The current size of the binary blob is expected to be 149 bytes or larger
