[PATCH] arm64: dts: sun50i-a64-pinephone: Add mount matrix for accelerometer

[Andrey Skvortsov]

From: Ondřej Jirman <megi at xff.cz>

accelerometer is mounted the way x and z-axis are invereted, x and y
axis have to be spawed to match device orientation.
The mount matrix is based on PCB drawing and was tested on the device.
