Subject: [PATCH 3/3] ARM: dts: qcom: msm8226-microsoft-common: Add inertial sensors

Add nodes for the Asahi Kasei AK09911 magnetometer and the Kionix
KX022-1020 accelerometer, both of which are connected over i2c2, in the
common device tree for msm8x26 Lumias.

Moneypenny (Lumia 630) does not have a magnetometer, and so the node is
deleted.
Tesla's (Lumia 830's) magnetometer is currently unknown.
