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.

Catch up with HEAD (r280229-r284686).

Remove MAXBSIZE use from drivers where it has nothing to do.

In some cases limits are just not needed, in others -- DFLTPHYS is the
right constant to use instead.

Remove FreeBSD 4.x compat shims. Verified by md5.

Add locking to mlx(4) to make it MPSAFE along with some other fixes:
- Use callout(9) rather than timeout(9).
- Add a mutex as an I/O lock that protects the adapter and is used
for the I/O path.

Add locking to mlx(4) to make it MPSAFE along with some other fixes:
- Use callout(9) rather than timeout(9).
- Add a mutex as an I/O lock that protects the adapter and is used
for the I/O path.
- Add an sx lock as a configuration lock that protects the relationship
of configured volumes.
- Freeze the request queue when a DMA load is deferred with EINPROGRESS
and unfreeze the queue when the DMA callback is invoked.
- Explicitly poll the hardware while waiting to submit a command to
allow completed commands to free up slots in the command ring.
- Remove driver-wide 'initted' variable from mlx_*_fw_handshake() routines.
That state should be per-controller instead. Add it as an argument
since the first caller knows when it is the first caller.
- Remove explicit bus_space tag/handle and use bus_*() rather than
bus_space_*().
- Move duplicated PCI device ID probing into a mlx_pci_match() routine.
- Don't check for PCIM_CMD_MEMEN (the PCI bus will enable that when
allocating the resource) and use pci_enable_busmaster() rather than
manipulating the register directly.

Tested by: no one despite multiple requests (hope it works)
