Input: atmel_mxt_ts - remove unnecessary platform data
It is not necessary to download these values to the maXTouch chip on every probe, since they are stored in NVRAM. It makes life difficult when tuning the device to keep them in sync with the config array/file, and requires a new kernel build for minor tweaks. These parameters only represent a tiny subset of the available configuration options, tracking all of these options in platform data would be a endless task. In addition, different versions of maXTouch chips may have these values in different places or may not even have them at all. Having these values also makes life more complex for device tree and other platforms where having to define a static configuration isn't helpful.
