Subject: [PATCH] cris: Convert ffs from an object-like macro to a function-like macro

This avoids bad interactions with code using identifiers called "ffs":

drivers/usb/gadget/f_fs.c: In function 'ffsmod_init':
drivers/usb/gadget/f_fs.c:2693:494: error: 'ffsusb_func' undeclared (first use in this function)
drivers/usb/gadget/f_fs.c:2693:494: note: each undeclared identifier is reported only once for each function it appears in
drivers/usb/gadget/f_fs.c: In function 'ffsmod_exit':
drivers/usb/gadget/f_fs.c:2693:677: error: 'ffsusb_func' undeclared (first use in this function)
drivers/usb/gadget/f_fs.c: At top level:
drivers/usb/gadget/f_fs.c:2693:35: warning: 'kernel_ffsusb_func' defined but not used [-Wunused-variable]
drivers/usb/gadget/f_fs.c: In function 'ffsmod_init':
drivers/usb/gadget/f_fs.c:2693:15: warning: control reaches end of non-void function [-Wreturn-type]
