First cut of new HW support from LSI and merge into FreeBSD.
Supports Drake Skinny and ThunderBolt cards.

Fixed botched merge of Skinny support and enhanced handling

Move mfi_decode_evt() to taskqueue.

Implement MFI_DEBUG for 64bit S/G lists.

Restore structure layout by reverting the array header to
use [0] instead of [1].

Add more Thunderbolt variants.

Don't act on events prior to boot or when shutting down.
Add hw.mfi.detect_jbod_change to enable or disable acting
on JBOD type of disks being added on insert and removed on
removing. Switch hw.mfi.msi to 1 by default since it works
better on newer cards.
MFhead_mfi r233016
Release driver lock before taking Giant when deleting children.
Use TAILQ_FOREACH_SAFE when items can be deleted. Make code a
little simplier to follow. Fix a couple more style issues.
MFhead_mfi r233620
Update mfi_spare/mfi_array with the actual number of elements
for array_ref and pd. Change these max. #define names to avoid
name space collisions. This will require an update to mfiutil
It avoids mfiutil having to do a magic calculation.
Add a note and #define to state that a "SYSTEM" disk is really
what the firmware calls a "JBOD" drive.
Thanks to the many that helped, LSI for the initial code drop,
mav, delphij, jhb, sbruno that all helped with code and testing.
can be enabled via the hw.mfi.msi tunable. Many mfi(4) controllers also
support MSI-X, but in testing it seems that many adapters do not work with
MSI-X but do work with MSI.

Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI
cards.
Initial code was supplied by LSI under BSD license. Several improvements
were done by myself. Such things like making it work in a static kernel,
be able to boot of the RAID, performance improvements. I removed some
fairly complicated code that seemed to directly access the disks under
the firmware. It doesn't seem to be needed and significantly slowed
down the performance of the driver and caused tons of sense errors to
be reported.
This code is being checked in this area so others can help me get it into
shape to commit into the FreeBSD tree. Assistance has been volunteered
by iXsystems.
We might want to re-work the JBOD attachment that creates /dev/mfisyspd?
node for each disk.
Performance is faster then prior cards. It works okay with WITNESS
and INVARIANTS on amd64 and i386. I recall seeing a use after
free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS
and INVARIANTS on.
First task is get all of the new structures to be named in FreeBSD
style format.
Next is probably to deal with the 64bit addressing changes that are
mostly around the #ifdef __amd64__ checks.
Thanks to LSI for providing the initial code.

now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now. This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.
