Input: cyttsp4 - remove driver
The cyttsp4 touchscreen driver was contributed in 2013 and since then has seen no updates. The driver uses platform data (no device tree support) and there are no users of it in the mainline kernel. There were occasional fixes to it for issues either found by static code analysis tools or via visual inspection, but otherwise the driver is completely untested. Remove the driver.
