integration_platforms help us control what get built/executed in CI and
for each PR submitted. They do not filter out platforms, instead they
just minimize the amount of builds/testing for a particular
tests/sample.
Tests still run on all supported platforms when not in integration mode.

Many driver samples or tests only had 'drivers' as the tag, without a
tag indicating what driver that is exactly, so add some missing tags.
