This patch adds FW versions stored in the flash to devlink info_get
callback.  Return the correct fw.psid running version using the
newly added bp->nvm_cfg_ver.

This will not cause an error to be returned for the entire operation on
older FW or HW, right?

return bnxt_dl_info_put(bp, req, BNXT_VERSION_STORED,
			DEVLINK_INFO_VERSION_GENERIC_FW_ROCE, roce_ver);

I don't think so.  This firmware call has been around for many years.
The call was recently extended to return the stored version
information but older firmware will still return successfully without
the stored versions.  I'll ask Vasundhara to double check on this.

Yes, older firmware will return success and does not set the new flag
support for stored firmware versions. Only in error cases, older or
newer FW will return error. Thanks.
