Subject: [PATCH v3 3/3] arm64: dts: qcom: msm8916-acer-a1-724: Add accelerometer/magnetometer

Iconia Talk S 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.
