Instead of putting object files inside libzephyr.a, simply
build a separate static library for the top level of sensor
drivers. Also, for those that were not building its own

drivers are building their own static libraries.

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.
