serial: sunzilog: Mark sunzilog_putchar() __maybe_unused
If CONSOLE_POLL=n, CONFIG_SERIAL_SUNZILOG_CONSOLE=n, and CONFIG_SERIO=m:
drivers/tty/serial/sunzilog.c:1128:13: error: ‘sunzilog_putchar’ defined but not used [-Werror=unused-function]
1128 | static void sunzilog_putchar(struct uart_port *port, int ch)
| ^~~~~~~~~~~~~~~~
Fix this by marking sunzilog_putchar() __maybe_unused.
