zephyr: motion: add support for runtime probing of motion sensors
Add possibility to define alternative motion sensors that
will be probed on EC boot.
This will allow to easily specify different variants of boards with
different motion sensors.
BRANCH=main
BUG=b:194424288
TEST=This commit shouldn't change anything.
Build, flash EC and motion sensors should work correctly,
detecting tablet mode and orientation changes.
