Input: synaptics-rmi4 - add support for F55 sensor tuning
Sensor tuning support is needed to determine the number of enabled tx and rx electrodes for use in F54 functions. The number of enabled electrodes is not identical to the total number of electrodes as reported with F55:Query0 and F55:Query1. It has to be calculated by analyzing F55:Ctrl1 (sensor receiver assignment) and F55:Ctrl2 (sensor transmitter assignment). Support for additional sensor tuning functions may be added later.
