[PATCH 4.4 38/86] Input: xpad - remove unused function

[ Upstream commit a6ed4a18ba6a6f5a01e024b9d221d6439bf6ca4c ]

There are two definitions of xpad_identify_controller(), one is used
when CONFIG_JOYSTICK_XPAD_LEDS is set, but the other one is empty
and never used, and we get a gcc warning about it:

drivers/input/joystick/xpad.c:1210:13: warning: 'xpad_identify_controller' defined but not used [-Wunused-function]

This removes the second definition.
