Input: touchscreen - broaden use-cases described in comments
Now that the helper functions have been moved to drivers/input/ so that all input devices may use them, the introductory comments can be updated to remove any implication that the helper functions are solely limited to touchscreens. This patch also scrubs any remaining use of 'DT' since there isn't any actual dependency on OF. A minor spelling error is resolved as well ('setups' -> 'sets up').
