Toradex OAK USB +/-10V 8channel ADC interface

uoakv* at uhidev?

The uoakv driver provides support for the Toradex OAK 10V device. The sensor possesses a collection of sensor values which are made available through the sysctl(8) interface.
The ADC date unit is "VDC"(DC voltage) and the value is signed. Because the Analog-Digital conversion cycle of the device is faster than the sensor framework update cycle, the driver keeps maximum/minimum/average values of each cycle as independent sensors.
The device has a unique serial number, indicated in the description part of the sensor value.
