The BMI260 accelerometer in the OneXPlayer Super X is exposed through
the ACPI BMI0160 ID. Its X and Y axes do not match the built-in display
axes, and no firmware mount matrix is provided.
Add an exact vendor and product DMI match with the matrix verified on
the hardware. The matrix keeps the native landscape position normal and
maps both portrait rotations to the corresponding display orientation.
Tested with iio-sensor-proxy 3.8 and Mutter 49.7 in all display
orientations. The compiled hwdb entry also matches the complete modalias
reported by the device.
