Linus Walleij 2f23cda3bf ARM: ux500: configure the sensors on the TVK board correctly
The U8500 HREF TVK board actually has a large set of sensors, with
their interrupt lines connected using open drain electronics.
Configure the two accelerometers and two magnetometers so we get
all sensors to actually probe on boot.
