serial: Delete dead code for CIR serial ports
Commit e4fda3a04275 ("serial: don't register CIR serial ports") adds a check for PORT_8250_CIR to serial8250_register_8250_port(). But the code isn't needed as the function never takes the branch when the port is CIR serial port. This patch deletes the dead code.
