zephyr: sensors: Add alternate sensors support
In some boards there's a runtime decision for which sensor to use. In
order to support this we'll need an instance of the alternate sensors
as well as a mapping for them.
Add an optional phandle `alternate-for` to the base sensors bindings.
When used, the sensor will be excluded from the primary
motion_sensors array and added instead to the motion_sensors_alt
array.
