MFC r253980 - new pciids for ciss(4) support

MFC r230313, r230316, r230323, r230588

Support new raid controllers

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Add support for the P212, P410, P410i, P411, and P812 HP Smart Array
controllers.

Submitted by: Scott Benesh at HP

Add `hw.ciss.nop_message_heartbeat' tunable (default disabled) for
NOP-message polling in ciss_periodic().
Note that setting the tunable to non-zero can be workaround only for
`ADAPTER HEARTBEAT FAILED' problem, and may freeze the system w/o
the problem.

Convert to use a SYNPOSIS section that mentions kernel modules.
Also add "device scbus" where needed.

Update PCI ids to add the E200, E200i, P400, and P400i storage
controllers. Remove the E400 since it is not a real product.

- Add a HARDWARE section which lists supported devices.

Mechanically kill hard sentence breaks and double whitespaces.

Document the new passthrough interface.

Add HP Smart Array 6422 and V100 to the list of supported controllers.

Add support for the HP Modular Smart Array 20 & 500 storage arrays.
Logical volumes on these devices show up as LUNs behind another
controller (also known as proxy controller). In order to issue
firmware commands for a volume on a proxy controller, they must be
targeted at the address of the proxy controller it is attached to,
not the Host/PCI controller.

A proxy controller is defined as a device listed in the INQUIRY
PHYSICAL LUNS command who's L2 and L3 SCSI addresses are zero. The
corresponding address returned defines which "bus" the controller
lives on and we use this to create a virtual CAM bus.

A logical volume's addresses first byte defines the logical drive
number. The second byte defines the bus that it is attached to
which corresponds to the BUS of the proxy controller's found or the
Host/PCI controller.

Change event notification to be handled in its own kernel thread.
This is needed since some events may require the driver to sleep
on some operations and this cannot be done during interrupt context.
With this change, it is now possible to create and destroy logical
volumes from FreeBSD, but it requires a native application to
construct the proper firmware commands which is not publicly
available.

Special thanks to John Cagle @ HP for providing remote access to
all the hardware and beating on the storage engineers at HP to
answer my questions.

Synchronize the list of support devices with the driver source code.

Add a COMPATIBILITY section. Note what is not supported.
