[Qemu-ppc] [PATCHv2 2/7] adb.c: include ADBDevice parent state in KBDState and MouseState

[Mark Cave-Ayland]

The parent ADBDevice contains the device id on the ADB bus. Make sure that
this state is included in both its subclasses since some clients (such as
OpenBIOS) reprogram each device id after enumeration.
