Benjamin Berg dda3ec0aa6 platform/x86: thinkpad_acpi: Implement tablet mode using GMMS method
Many thinkpad laptops and convertibles provide the GMMS method to
resolve how far the laptop has been opened and whether it has been
converted into tablet mode. This allows reporting a more precise tablet
mode state to userspace.

The current implementation only reports a summarized tablet mode state
which is triggered as soon as the input devices become unusable as they
are folded away from the display.

This will work on all models where the CMMD method was used previously and
it may also work in other cases.

Thanks to Peter Zhang of Lenovo for providing information on how to use the
GMMS method to query the tablet mode.
