Jim Harris f11c7f6305 Add isci(4) driver for amd64 and i386 targets.
The isci driver is for the integrated SAS controller in the Intel C600
(Patsburg) chipset.  Source files in sys/dev/isci directory are
FreeBSD-specific, and sys/dev/isci/scil subdirectory contains
an OS-agnostic library (SCIL) published by Intel to control the SAS
controller.  This library is used primarily as-is in this driver, with
some post-processing to better integrate into the kernel build
environment.

isci.4 and a README in the sys/dev/isci directory contain a few
additional details.

This driver is only built for amd64 and i386 targets.
