[PATCH v3 1/2] dt-bindings: input: focaltech,ft8112: Add focaltech,ft3d81 compatible

[Pradyot Kumar Nayak]

The Focaltech ft3d81 is fully compatible with the ft8112 i.e.
it uses the same I2C-HID protocol and the same power-on/reset sequencing,
DT nodes for boards carrying an ft3d81,can therefore bind to the existing
ft8112 driver without any additional changes.
