for 5.3-rc2: I/imx8 5.3 rc1 devkit/accel gyro updates
requested to merge martin.kepplinger/linux-next:i/imx8-5.3-rc1-devkit/accel_gyro_updates into imx8-linux-next-devkit
Many st_lsm6dsx driver updates from upstream (after reverting initial changes we've had so far).
This also includes a bugfix and should provide iio-sensor-proxy with correct orientation states.
