drivers: Use SPDX identifiers
Convert the remaining files in src/drivers to use SPDX identifiers.
int15.h and default_brightness_levels.asl did not have license headers,
but they were both copied from other GPL2 files, so they should be under
the GPL2 as well.
ne2k.c and drm_dp_helper.h are licensed under custom BSD-like licenses
that do not have an SPDX equivalent, so they are added as exceptions
to the license header lint.
