adb: Switch bus reset to 3-phase-reset

Browse source 
Switch the ADB bus from using BusClass::reset to the Resettable
interface.

This has no behavioural change, because the BusClass code to support
subclasses that use the legacy BusClass::reset will call that method
in the hold phase of 3-phase reset.
