Geert Uytterhoeven d142585bce serial: cpm_uart: Protect udbg definitions by CONFIG_SERIAL_CPM_CONSOLE

If CONFIG_CONSOLE_POLL=y, and CONFIG_SERIAL_CPM=m (hence
CONFIG_SERIAL_CPM_CONSOLE=n):

    drivers/tty/serial/cpm_uart/cpm_uart_core.c:1109:12: warning: ‘udbg_cpm_getc’ defined but not used [-Wunused-function]
     1109 | static int udbg_cpm_getc(void)
	  |            ^~~~~~~~~~~~~
    drivers/tty/serial/cpm_uart/cpm_uart_core.c:1095:13: warning: ‘udbg_cpm_putc’ defined but not used [-Wunused-function]
     1095 | static void udbg_cpm_putc(char c)
	  |             ^~~~~~~~~~~~~

Fix this by making the udbg definitions depend on
CONFIG_SERIAL_CPM_CONSOLE, in addition to CONFIG_CONSOLE_POLL.
