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 driver used the if_watchdog timer both as a watchdog on transmit and
auto-negotiation. To make this simpler and easier to understand I have
split this out into two separate timers. One just manages the auto-neg
side of things and one is a transmit watchdog. Neither uses if_watchdog.

Fixup locking in if_my(4) and mark it MPSAFE:
- Add locked variants of my_start() and my_init().
- Assert that the lock is held in several places rather than recursing.
- Overhaul failure case handling in my_attach() so that it will actually
clean up completely in each of the failure cases.
- Setup the interrupt after ether_ifattach() in my_attach().
- Remove unused callout handle from softc.
- Free the metadata for the descriptors my_in detach() (we leaked it
before).
- Fix locking in my_ioctl().
- Remove spls.

Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.

with several differences. Myson sells this chip to several

that respond to this driver. Myson will be supplying a list
of some of these.
