Input: mms114 - drop platform data and use generic APIs
The MMS114 platform data has no in-tree users, so drop it. Switch to using the standard touchscreen properties via touchscreen_parse_properties(), and move the old DT parsing code to use device_property_*() APIs. Finally, use touchscreen_report_pos to report x/y coordinates and drop the custom x/y inversion code.
