mac_via: implement ADB_STATE_IDLE state if shift register in input mode
NetBSD switches directly to IDLE state without switching the shift register to
input mode. Duplicate the existing ADB_STATE_IDLE logic in input mode from when
the shift register is in output mode which allows the ADB autopoll handler to
handle the response.
