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.

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.

Minor updates as a precursor to fixing sbp_targ

firewire.c -- expand a comment and repair a typo
sbp.h -- define Logical Unit Reset so it can be used in sbp_targ

Change u_intXX_t to uintXX_t. Change a couple of 'unsigned long's to
uint32_t where appropriate.

MFp4:
- Introduce sbp_targ_login instead of sbp_targ_istate.
- Implement reconnection and logout.
- Freeze simq while bus reset.

Oops, fix typo in my name.
