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.

Change reporting of a "SYSTEM" disk to "JBOD" to match

This means that fiutil command to "create jbod" is now a

and support added to really create LSI JBOD and enable that
feature on cards that support it.

Improve battery capacity reporting

When a status pointer is passed in mfi_dcmd_command does not return an
errno (if the ioctl is successful), so move the test for NO_HW_PRESENT
outside of the error case. This should fix incorrect reporting for
systems with a dead or no battery.

Additionally, handle error codes other than NO_HW_PRESENT by omitting
the battery capacity display. LSI's supercap-based parts (CV series)
report their data using the same interface as battery-based parts,
except that they do not include the capacity stats (state of charge,
cumulative charge cycles, etc.)

This does not replace MegaCLI, found in ports, as that is officially sanctioned

is open source and guaranteed to provide basic functionality, which can be
especially useful if you have a problem and can't get MegaCLI to work.
