arm64: dts: allwinner: pinephone: Add mount matrix to accelerometer

The way InvenSense MPU-6050 accelerometer is mounted on the user-facing side
of the Pine64 PinePhone mainboard, which makes it rotated 90 degrees counter-
clockwise, [1] requires the accelerometer's x- and y-axis to be swapped, and
the direction of the accelerometer's y-axis to be inverted.

Rectify this by adding a mount-matrix to the accelerometer definition in the
Pine64 PinePhone dtsi file.
