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

[Erikas Bitovtas <xerikasxx@gmail.com>]

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.

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

This device uses Capella CM36686 as its ambient light and proximity
sensor. Downstream device tree uses the compatible of CM36283, but upon
probe, we can see that a device ID of CM36686 is actually read. Possibly
a driver for CM36283 was adapted to be used on CM36686.
This patch enables Capella CM36686 ambient light and proximity sensor on
Asus ZenFone 2 Laser/Selfie.
