otgcontrol: add debug hack disabling OTG detection in default state 

Due to the authorized mode (default state) not being implemented
properly yet with filtering and such, a concern regarding short
while in a bag or such was discussed.

As a hot fix, the device connection (POGO ID pin) is deactivated
in default mode until this has been properly implemented, but
enabled when explicitly entering unauthorized mode from the
test-application in order to use the QR code reader.
