Martin Blapp 7633e7f1a2 ServeRaid (at least 5i) didn't initialize correctly. To get
them working (cache, automatic rebuild and hotswap) the FFDC
info (First Failure Data Capture) on the adapter must be
initialised.

Logical drives in critical/degraded states weren't added to
the drive list. FreeBSD was not able to see a degraded array
after a reboot. Degraded drives are now also added to the drivelist
and the state of the logical drive is given at boottime.

The adapter type is detected from informations in nvram page 5
and displayed at boottime.

Change IPS_OS_FREEBSD definition from 10 to 8 according to IBM
specs.
