serial: core: Fix unused variable warnings from uart_console()
If CONFIG_SERIAL_CORE_CONSOLE=n, build warnings are generated by
uart_console() macro expansion:
drivers/tty/serial/of_serial.c: In function ‘of_serial_suspend_8250’:
drivers/tty/serial/of_serial.c:262:20: warning: unused variable ‘port’ [-Wunused-variable]
struct uart_port *port = &port8250->port;
^
drivers/tty/serial/of_serial.c: In function ‘of_serial_resume_8250’:
drivers/tty/serial/of_serial.c:272:20: warning: unused variable ‘port’ [-Wunused-variable]
struct uart_port *port = &port8250->port;
