[PATCH] arm64: dts: qcom: msm8916-longcheer-l8910: Add touchscreen

[Stephan Gerhold]

From: Jonathan Albrieux <jonathan.albrieux@xxxxxxxxx>

The BQ Aquaris X5 (Longcheer L8910) has a Himax HX852x-ES touchscreen,
which can now be described with the bindings recently added to linux-next.
Add it to the device tree to allow using the touchscreen.
