serial: suncore: Fix RSC/LOM handling in sunserial_console_termios().

Browse Source 
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.
