usb: pxa27x_udc: remove unused function argument
We get a warning for this when building with W=1 because the argument gets assigned to something else but never read: drivers/usb/gadget/udc/pxa27x_udc.c: In function 'stop_activity': drivers/usb/gadget/udc/pxa27x_udc.c:1828:74: error: parameter 'driver' set but not used [-Werror=unused-but-set-parameter] This remove the argument entirely.
