Add support to reconfigure a drive as SYSPD (real JBOD in LSI

terminology).

Adds command "mfiutil syspd <drive#>" to change a drive to SYSPD.  Drive
will then be scanned/reported immediately as /dev/mfisyspdX by the host.

"mfiutil good <drive#>" clears SYSPD mode, remove /dev/mfisyspdX and
sets disk into UNCONFIGURED mode.

Tested on Dell H310 SAS/SATA RAID controller.
