Add reverse battery protection

Need a diode between 12V and the VXO7805 power module.
I missed that the power module doesn't have reverse battery protection.
That became apparent when I accidentaly hooked the power up backwards.
That killed the power module which put 12V on the 5V output and killed the CAN transceiver.
Everything else was protected by the 3.3V regulator.
Profets were protected according to their datasheet.
