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.

@section scic_introduction_section Introduction
The Storage Controller Interface Core (SCIC) provides the underlying fundamental
hardware abstractions required to implement a standard SAS/SATA storage driver.
The following is a list of features that may be found in a core implementation:
-# hardware interrupt handling
-# hardware event handling
-# hardware state machine handling
-# IO and task management state machine handling
-# Phy staggered spin up
@image latex sci_core.eps "SCI Core Class Diagram" width=16cm
@note
For the SCU Driver Standard implementation of the SCI Core interface the
following definitions should be used to augment the cardinalities described
in the previous diagram:
-# There are exactly 4 scic_phy objects in the scic_controller.
-# There are exactly 4 scic_port objects in the scic_controller.
-# There can be a maximum of 4 scic_phy objects managed in a single scic_port.
-# The maximum number of supported controllers in a library is a truly flexible
value, but the likely maximum number is 4.
