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.

Revert agp_intel.c part of the r274040 for now. There is a confusion

Leave the agp_intel.c out of static compilation on amd64, it makes the
things consistent with agp.ko.

agp_intel.c provides support for AGP on Intel chipsets from 440/BX to

agp_intel.c provides support for AGP on Intel chipsets from 440/BX to
875. This intersects with the agp_i810.c, which supports all Intels
from i810 to Core i5/7. Both agp_intel.c and agp_i810.c are compiled
into kernel when device agp is specified in config, and agp_i810
attach seems to be selected by chance due to linking order.

Strip support for 810 and later from agp_intel.c. Since 440-class
chipsets do not support any long-mode capable CPUs, remove agp_intel.c
from amd64 kernel file list. Note that agp_intel.c is not compiled
into agp.ko on amd64 already.
