One way to do that is to have a "timeout" timer (e.g. 5 seconds) that
is reset on each read_remote_rssi call from HAL. On this timer
expires, Unregister is called.

Note that the comment I made on the patch itself regarding configuring
the period for readings apply here: I think there should be some way
to set this period. Otherwise, a two small period (say, 1s) will be
wasting power for an application that reads only every 5s or 10s. Or
the contrary, a too long timer will make applications which read more
frequent receive inaccurate readings.
