serial: remove back and forth conversions in serial_out_sync
The two callers to serial_out_sync() have a struct port right there in scope, but then pass in a struct 8250_port which then is locally resolved back to a struct port. Delete the needless back and forth and just pass in the struct port directly. Rename the function to have "_port" in its name, so the name <--> args relationship is consistent with the other serial_in/out vs serial_port_in/out function classes.
