Screen should not rotate automatically on a laptop

[cktenn]

There are recently more machines shipped with an accelerometer to bring about the automatic rotation feature on pad-like or 2in1 products. However, manufacturers sometimes share designs between platforms; a laptop may mount an accelerometer on its panel. The user experience on laptops with a fixed keyboard/touchpad that rotates automatically is somehow annoying, and the touchpad motion is confusing.

The SMBIOS specification defines chassis type in section 7.4.1. Softwares can determine to rotate automatically or not by checking this value, or at least not to rotate on a laptop(0x09) and notebook(0x0A).

The legitimate chassis type to enable the rotation feature should be:
Tablet (0x1E)
Convertible (0x1F)
Detachable (0x20)

[Sebastien Bacher (seb128)]

the rotation is being handled by iio-sensor-proxy and if such heuristic needs to be added it should probably be there. Could you also open a report upstream on gitlab to see what's their input on a such change?

A upstream MP for disabling rotation based on #4.

Based on some device doesn't config chassis type correctly, the patch can only be like
