arm64: dts: qcom: msm8939-asus-z00t: add ambient light and proximity sensor

This device uses Capella CM36686 as its ambient light and proximity
sensor. It is fully compatible with Vishay VCNL4040. Downstream device
tree reports Capella CM36283, but upon probe, a device ID for CM36686 is
actually found. This commit adds support for Capella CM36686 ambient
light and proximity sensor.
