HID: remove hid-ff

Browse Source 
hid-ff.c now calls only pidff (generic driver), the special ones are now
in separate drivers. Invoke pidff on all non-special directly.

Say Y here is you want force feedback support for a few HID devices.
See below for a list of supported devices.
See <file:Documentation/input/ff.txt> for a description of the force
feedback API.
If unsure, say N.

Say Y here if you have a PID-compliant device and wish to enable force
feedback for it. Microsoft Sidewinder Force Feedback 2 is one of such
