adb: add property to disable direct reg 3 writes
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.
