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.

[etherswitch] add ukswitch hint that is phy offset at mdio register

This patch allows to specify PHY register offset for ukswitch. For instance,
switch MAICREL KS8995XA connected via MDIO to SoC, but PHY register starts
at 1. So hint for this case is: hint.ukswitch.0.phyoffset=1

No change/effect if hint is not set.

The mdio driver interface is generally useful for devices that require
