Subject: [PATCH 4/8] arm64: dts: qcom: msm8939-samsung-a7: Add accelerometer/magnetometer

A7 uses a Bosch BMC150 accelerometer/magnetometer combo.
The chip provides two separate I2C devices for the accelerometer
and magnetometer that are already supported by the bmc150-accel
and bmc150-magn driver.
