Input: ressurect EVIOCGREP and EVIOCSREP
While writing to an event device allows to set repeat rate for an individual input device there is no way to retrieve current settings so we need to ressurect EVIOCGREP. Also ressurect EVIOCSREP so we have a symmetrical interface. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
