ARM: dts: ux500: samsung-golden: Add IMU (accelerometer + gyroscope)

Browse Source 
samsung-golden has a InvenSense MPU-6051M IMU that provides an
accelerometer and gyroscope. It seems to be functionally compatible
with MPU-6050 so we can easily enable it by adding the necessary
device tree nodes.
