[nrf fromtree] platform: nordic_nrf: Add SPDX tags to device_cfg.h files

The Apache-2.0 notice in these files is missing the punctuation of the
standard boilerplate, so license scanners cannot match it by full text,
and there is no SPDX tag to fall back on. Tools consequently report the
files as carrying no license at all.

Add an SPDX-License-Identifier tag stating the license each notice
already grants. This follows nrf9161dk_nrf9161, previously the only
Nordic board whose device_cfg.h carried a tag. The notice text itself
is left untouched.

All ten remaining Nordic device_cfg.h files share the same ARM header
and are covered here, so a newly added board no longer reintroduces the
problem.
