HID: add new driver for non-compliant Saitek devices
The driver currently only supports the PS1000 controller. It fixes the report descriptor by removing a non-existing axis and clearing the constant bit on the d-pad and button input reports. Signed-off-by: Andreas Hübner <andreas@k4n.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
