[PATCH 01/14] Input: atmel_mxt_ts - do not pass suspend mode in platform data

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

The way we are supposed to put controller to sleep and wake it up does not
depend on the platform, but rather on controller itself. Controllers using
T9 require manipulating T9 control register, while others, using newer
T100, should be put to sleep by adjusting T7 power config.

We'll keep pdata->suspend_mode for now and remove it when we rework
chromeos-laptop driver.
