Use the new module_hid_driver macro in all HID drivers that have a simple register/unregister init/exit. This also converts the hid drivers that test for a failure of hid_register_driver() and report the failure. Using module_hid_driver in those drivers removes the failure message.

* HID driver for Saitek devices, currently only the PS1000 (USB gamepad).

* Fixes the HID report descriptor by removing a non-existent axis and
|
|
* clearing the constant bit on the input reports for buttons and d-pad.
