mpi3mr: Honor the dma mask from IOCFacts

The number of signficant bits that are decoded are returned in the flags
field of the IOCFacts structure from the device. Rather than assume the
worst with a pessimal 32-bit maximum, look at this value and pass it
along to all the dma map creation requests.

A lof of those creations are repetitive and could just inherit from the
base tag if we moved to the templated interface. This is called out as
desireable future work not done at this time.

In addition, due to a chicken and an egg problem, we have to allocate
some of the maps with a 32-bit loaddr. These are the ones we need to
read iocfacts. And they are fine to be so restricted: they are little
used after startup, and when they are used, bouncing is fine.

mpi3mr: Reduce the scope of the reset_mutext

Reduce the scope of reset_mutext to protect the msleep in the watch dog
thread as well as the MPI3MR_FLAGS_SHUTDOWN bit. Use it to protect the
wakeup in mpi3mr_detach so this thread can exit sooner when we're trying
to do an orderly shutdown. Optimize the flow to check the sleep and
other conditions before going to sleep.

It's an open question if this should protect sc->unrecoverable, and if
we should wakeup the watchdog thread when we set it. We might also want
to move too booleans for the three flags that we have now in
mpi3mr_flags. There are a number of U8s that should really be bools and
we might want to also group them together to pack softc better.

mpi3mr: Move creation of watchdog to interupt config hook

Move creation of watchdog process from just before we configure the
interrupt config hook to into the config hook itself. This prevents it
from racing the config intr hook and doing an extra reset of the
card. This extra reset is usually harmless, but sometimes it can prevent
discovery of devices if done at just the wrong time. This can lead to no
disks being registered in a box full of disks, for example. Starting it
later eliminates this race, making discovery reliable.

mpi3mr: 3rd Generation Tri-Mode NVMe/SAS/SATA MegaRaid / eHBA

This is Broadcom's mpi3mr driver for FreeBSD version 8.6.0.2.0.
The mpi3mr driver supports Broadcom SAS4116-based cards in the 9600
series: 9670W-16i, 9670-24i, 9660-16i, 9620-16i, 9600-24i, 9600-16i,
9600W-16e, 9600-16e, 9600-8i8e.

Initially only available as a module and on amd64/arm64, since that's
how it has been tested to date. Future commits will add it to the kernel
build and may expand the architectures it is supported on.
