MacOS 9 has a bug in its PMU driver whereby after configuring the ADB bus devices it sends another write to reg 3 on both devices resetting them both back to the same address. Add a new disable_direct_reg3_writes property to ADBDevice to disable these direct writes which can enabled just for the upcoming pmu-adb support.
