[PATCH 7/6] dt-bindings: tda998x: add the calibration gpio

[Russell King]

Add the optional calibration gpio for integrated TDA9950 CEC support.
This GPIO corresponds with the interrupt from the TDA998x, as the
calibration requires driving the interrupt pin low.

Sorry, this patch got forgotten, tacking it on the end of the series.
