Mary Ruthven 8f118e0167 device_state: signal if device_set_state changed the state ...

Each device keeps track of the last known state. If device_set_state
updates the device state to a new known state, then return true. Cr50
uses this returned value to check if the state has changed instead of
calculating it itself.

BUG=none
BRANCH=none
TEST=device detection still works
