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.

Merge enhancements to the ALTERA Avalon bus generic device attachment
driver to support exposing a GEOM device, which can be used to mount
Avalon-attached ROMs, reserved areas of DRAM, etc, as a filesystem:

commit 9deb1e60eaaaf7a3687e48c58af5efd756f32ec6
Author: Robert N. M. Watson <robert.watson@cl.cam.ac.uk>
Date: Sat Mar 5 20:33:12 2016 +0000

Use format strings with make_dev(9) in avgen(4).

commit 0bf2176c23e7425bfa042c08a24f8a25fe6d8885
Author: Robert N. M. Watson <robert.watson@cl.cam.ac.uk>
Date: Tue Mar 1 10:23:23 2016 +0000

Implement a new "geomio" configuration argument to altera_avgen(4),
the generic I/O device we attach to various BERI peripherals. The new
option requests that, instead of exposing the underlying device via a
special device node in /dev, it instead be exposed via geom(4),
allowing it to be used with filesystems. The current implementation
does not allow a device to be exposed both for file/mmap and geom, so
one of the two models must be selected when configuring it via FDT or
device.hints. A typical use of the new option will be:

sri-cambridge,geomio = "rw";
