Peter Barker dabcf0e91c AP_Compass: make compass instance number part of AP_Compass_Backend
rather than each backend storing this itself.

This allows many methods to assume that they are working on the current instance number rather than being passed the instance number

registering the compass via the compass backend method now infers setting the device ID
