ARM: dts: Ux500: fix up TVK sensor data
- Fix the I2C address and supply line names for the AK8974 - Sets up the interrupt lines to the different components as they actually are connected, I was confused for some time by the fact that several lines were connected with <NM> 0 Ohm resistors, which means NOT MOUNTED and is thus not 0 Ohm at all but infinite ohms, i.e. not connected at all.
