Subject: [PATCH 1/3] arm64: dts: qcom: msm8916-samsung-fortuna: Add BMC150 accelerometer/magnetometer

From: Joe Mason <buddyjojo06@...look.com>

Some Grand Prime use 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.

[Stephan: Move sensors to common dtsi, disabled by default]

[Raymond: Add it to grandprimelte. Use interrupts-extended]
