Input: remove old USB touchscreen drivers
itmtoch, mtouchusb and touchkitusb have been replaced with composite usbtouchscreen driver and can be removed now. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

- *
- * Kudos to ITM for providing me with the datasheet for the panel,
- * even though it was a day later than I had finished writing this
- * driver.
- *
- * It has meant that I've been able to correct my interpretation of the
- * protocol packets however.
- *
- * CC -- 2003/9/29
- *
- * History
- * 1.0 & 1.1 2003 (CC) vojtech@suse.cz
- * Original version for 2.4.x kernels
- *
- * 1.2 02/03/2005 (HCE) hc@mivu.no
- * Complete rewrite to support Linux 2.6.10, thanks to mtouchusb.c for hints.
- * Unfortunately no calibration support at this time.
- *
- * 1.2.1 09/03/2005 (HCE) hc@mivu.no
- * Code cleanup and adjusting syntax to start matching kernel standards
- *
- * 1.2.2 10/05/2006 (MJA) massad@gmail.com
- * Flag for detecting if the screen was being touch was incorrectly
- * inverted, so no touch events were being detected.

- * Changed reset from standard USB dev reset to vendor reset
- * Changed data sent to host from compensated to raw coordinates
- * Eliminated vendor/product module params
- * Performed multiple successful tests with an EXII-5010UC
- *
- * 1.5 02/27/2005 ddstreet@ieee.org
- * Added module parameter to select raw or hw-calibrated coordinate reporting
