usb: fix usb_fdt_support.c when altq enabled (usb_ehernet.h changes)

usb: fix usb_fdt_support.c when altq enabled (usb_ehernet.h changes)

After r351243 when ALTQ was enabled in the kernel, the inline functions
in ifq.h would not have full type information as if_var.h was not
included.

Given usb_ethernet.h already includes all the various headers (which)
is the cause of the problem here, add if_var.h to it. This fixes the
builds again.

usb_ethernet.h includes a number of mii headers, but only does so in
order to have struct mii_data available. However, it only really needs
a forward declaration of struct mii_data for use in pointer form for
the return type of a function prototype.

Custom kernel configuration that have usb and fdt enabled, but no miibus,
end up with compilation failures because miibus_if.h will not get
generated.

Due to the above, the following changes have been made to usb_ethernet.h:
* remove the inclusion of mii headers
* forward-declare struct mii_data
* include net/ifq.h to satify the need for complete struct ifqueue

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.

This change makes it possible to define driver specific attach
handler such that driver can announce interface capabilities and
can do its own MII attach. Currently all USB ethernet controllers
have no way to establish a link with pause capabilities. Lack of
checksum offloading support also was one of reason to bring this
change in.

This change adds a couple of wrappers to USB ethernet drivers
(uether_ifmedia_upd, uether_init and uether_start). All exported
functions in uether has prefix uether_ so I think it's more
consistent to have wrappers that follow the convention.
This change preserves ABI/KPI so it should be safe to merge this
change to stable/8.

While I'm here add missing __FBSDID and clean up headers.
