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.

Merge head up to r262222 (last merge was incomplete).

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

As it turns out, MSIs are broken with 2820SA so introduce an AAC_FLAGS_NOMSI
quirk and apply it to these controllers [1]. The same problem was reported
for 2230S, in which case it wasn't actually clear whether the culprit is the
controller or the mainboard, though. In order to be on the safe side, flag
MSIs as being broken with the latter type of controller as well. Given that
these are the only reports of MSI-related breakage with aac(4) so far and
OSes like OpenSolaris unconditionally employ MSIs for all adapters of this
family, however, it doesn't seem warranted to generally disable the use of
MSIs in aac(4).
While it, simplify the MSI allocation logic a bit; there's no need to check
for the presence of the MSI capability on our own as pci_alloc_msi(9) will
just fail when these kind of interrupts are not available.

Merge fresh head.

Allow unmapped I/O via aacd(4). It shouldn't be too hard to add the
same support for aacp(4), I'm lacking the necessary hardware for
testing, though.

- Remove pointless returns.
- Make cm_data a void pointer and cm_flags unsigned as appropriate.

- Make tables, device ID strings etc const. This includes #ifdef'ing 0
aac_command_status_table, which is actually unused since r111532.
While at it, make aac_if a pointer to the now const interface tables
instead of copying them over to the softc (this alone already reduces the
size of aac.ko on amd64 by ~1 KiB).
- Remove redundant softc members.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
- Remove redundant bzero(9)'ing of the softc.
- Use pci_enable_busmaster(9) instead of duplicating it.
- Remove redundant checking for PCIM_CMD_MEMEN (resource allocation will
just fail).
- Canonicalize the error messages in case of resource allocation failures.
- Add support for using MSI instead of INTx, controllable via the tunable
hw.aac.enable_msi (defaulting to on).

- Fix races on setting AAC_AIFFLAGS_ALLOCFIBS
- Remove some unused AAC_IFFLAGS_* bits.
Please note that the kthread still makes a difference between the
total mask and AAC_AIFFLAGS_ALLOCFIBS because more flags may be
added in the future to aifflags.
