Earlycon now shares a common framework in linux-next.
The EARLYCON_DECLARE() can be deleted and the OF_EARLYCON_DECLARE()
can all share the same earlycon name. iow,
-EARLYCON_DECLARE(cdns, cdns_early_console_setup);
+OF_EARLYCON_DECLARE(cdns, "xlnx,xuartps", cdns_early_console_setup);
+OF_EARLYCON_DECLARE(cdns, "cdns,uart-r1p8", cdns_early_console_setup);
+OF_EARLYCON_DECLARE(cdns, "cdns,uart-r1p12", cdns_early_console_setup);
