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

Add crashdump support to the ips driver. It only works for the more modern

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.

Logical drives in critical/degraded states weren't added to
the drive list. FreeBSD was not able to see a degraded array
after a reboot. Degraded drives are now also added to the drivelist
and the state of the logical drive is given at boottime.

The adapter type is detected from informations in nvram page 5
and displayed at boottime.

- Zero the buffers used to hold configuration data from the card. Not doing
so can leave stale data in the buffer and confuse the driver.
- enable the ability to set the 'disable' hint for the driver to keep it
from attaching. i.e. 'hw.ips.0.disable=1' will prevent the driver from
attaching.
- Only detach if attach suceeded.
