arm64: dts: allwinner: sun50i-a64-pinephone: Fix mpu6050 mount matrix

Browse source

The current mount matrix for mpu6050 is wrong. The mount matrix is a
simple transform from the sensor coordinate space to the device
coordinate space described in DT, where, looking at the screen, X
points to the right, Y to the top, and Z towards the user.

The mpu6050 is mounted like this (looking at the screen from the
front; the sensor is on the near side of the PCB, so its Z axis
points towards the user; o marks the pin 1 corner):

           +Xs
            ^
            |
         +------+
  +Ys <--|      |
         | o    |
         +------+

so this gives:

  Xd = -Ys  [0, -1, 0]
  Yd =  Xs  [1, 0, 0]
  Zd =  Zs  [0, 0, 1]
