wl1251: remove wl1251_ops
Now wl1271 is splitted to separate files, no need to use wl1251_ops anymore. So remove struct wl1251_chip and wl1251_ops.c. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Reviewed-by: Vidhya Govindan <vidhya.govindan@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
