Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

We assumed that ${BOARD} and ${BOARD_FAMILY} are always the same and
thus interchangeable. That isn't always the case so use ${BOARD} proper
for when we mean the exact BOARD name we are building for vs the
BOARD_FAMILY.
We also add .dts files for board variants within a board family, such
that we have a .dts matching each board name.
