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.

Overhaul error handling in the IPS driver. Don't use a magic value for
driver-induced errors, instead be better about propagating error status
upwards. Add more error definitions, courtesy of the linux driver. Fix
a command leak in the ioctl handler. Re-arrange some of the command handlers
to localize error handling.

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64. The optimization is a trivial on recent machines.

Add crashdump support to the ips driver. It only works for the more modern
ServeRAID 4 - 7 models right now. Support for older cards is possible, but
I don't have any hardware to experiment with.

Lock the IPS driver and bring it out from under Giant. Also do some
significant clean up and optimizations:
- don't call bioq_disksort() on every command, the hardware will do that for
us.
- remove all of the complicated bio deferral code. bio's that can't be
serviced immediately can just wait on the bioq.
- Only reserve one command object for doing control commands to the card.
This simplifies a lot of code and significantly reduces the size of the
command struct.
- Allocate commands out of a slab instead of embedding them into the softc.
- Call the command action method directly instead of having ips_get_free_cmd()
call it indirectly.
