serial: suncore: Fix RSC/LOM handling in sunserial_console_termios().
RSC and LOM devices have fixed speed settings. We already had some code to match and handle "rsc" named devices on E250 systems, but we also have to handle 'rsc-console', 'rsc-control', and 'lom-console'. Also, in order to get this right regardless of what 'output-device' happens to be, explicitly pass the UART device node pointer to this routine. Signed-off-by: David S. Miller <davem@davemloft.net>
