This mode was selected through the platform data, but it can be chosen by the driver internally without platform data configuration. How to decide the control mode: If the PWM period has specific value, the mode is PWM input. On the other hand, the mode is register-based. This mode selection is done on the _probe(). Move 'mode' from a header file to the driver private data structure, 'lp855 x'. And correlated code was replaced.
