sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

sys/dev: minor spelling fixes.

Give panic format string to pacify clang warning.

Whitespace cleanup, in advance of next sync with Adaptec's driver. No
functional change.

Sync with the official Adaptec vendor driver:

[1] Add the support for the NARK controller which seems a variant of

Sync with the official Adaptec vendor driver:

[1] Add the support for the NARK controller which seems a variant of
the i960Rx.
[2] Split up memory regions and other resources in 2 different parts
as long as NARK uses them separately (it is not clear to me
why though as long as there are no more informations available
on this controller). Please note that in all the other cases,
the regions overlaps leaving the default behaviour for all the
other controllers.
[3] Implement a clock daemon responsible for maintain updated the
wall clock time of the controller (run any 30 minutes)*.

* Please note that originally, in the Adaptec driver, the clock daemon
is not implemented with callouts as in our in-tree driver.

Diff reduction to Adaptec's driver (around build 15317): catch up with a

aac_intr0 rotted long ago, remove it.

Retire the FreeBSD 4.x compat code and __FreeBSD_version checks from the aac
driver.

Complete the repo-copy of aac_ioctl.h from sys/dev/aac/to sys/sys.

Cast printf'ed values to intmax_t.

Remove the use of AACQ_COMPLETE here since there is no longer a completion
queue.

Use __FBSDID().
Also some minor style cleanups.

Major bugfixes for large memory and fast systems.

aac.c:
Re-arrange the interrupt handler to optimize the common case of
the adapter interrupting us because one or more commands are complete,
and do a read across the pci bus to ensure that all posted status
writes are flushed. This should close a race that could cause command
completion interrupts to be lost.
Follow the spec a bit closer when filling out command structures.
Enable the Fast Response feature to eliminate the need for the card
to DMA successfull command completions back into host memory.
Tell the controller how much physical memory we have. Without this
there was a chance that our DMA regions would collide with the
memory window used by the cache on the controller. The result would
be massive data corruption. This seemed to mainly affect systems with
>2GB of memory.
Fix a few whitespace problems.

aac_debug.c:
Add an extra diagnostic when printing out commands.

aac_disk.c:
Add extra sanity checks.

aacreg.h:
Prepare for making this 64-bit clean by reducing the use of enumeration
types in structures.

Many thanks to Justin Gibbs for helping track these down.

1. Implement poll(). This will check for queued aif's so that a
subsequent ioctl call to retrieve the next aif will not block.
2. Don't catch signals when sleeping on a fib sent from userland. This
causes a race and panic due to the pthread context switcher waking
up the tsleep at inopportune times.
