Input: add support for the STMicroelectronics FingerTip touchscreen
The stmfts (ST-Microelectronics FingerTip S) touchscreen device is a capacitive multi-touch controller mainly for mobile use. It's connected through i2c bus at the address 0x49 and it interfaces with userspace through input event interface. At the current state it provides a touchscreen multitouch functionality up to 10 fingers. Each finger is enumerated with a distinctive id (from 0 to 9). If enabled the device can support single "touch" hovering, by providing three coordinates, x, y and distance. It is possible to select the touchkey functionality which provides a basic two keys interface for "home" and "back" menu, typical in mobile phones.
