arch/m68k/apollo/config.c:111:5: warning: no previous prototype for ‘dn_serial_console_wait_key’ [-Wmissing-prototypes]
111 | int dn_serial_console_wait_key(struct console *co) {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
arch/m68k/apollo/config.c:118:6: warning: no previous prototype for ‘dn_serial_console_write’ [-Wmissing-prototypes]
118 | void dn_serial_console_write (struct console *co, const char *str,unsigned int count)
| ^~~~~~~~~~~~~~~~~~~~~~~
arch/m68k/apollo/config.c:238:6: warning: no previous prototype for ‘dn_dummy_waitbut’ [-Wmissing-prototypes]
240 | void dn_dummy_waitbut(void) {
| ^~~~~~~~~~~~~~~~

Fix this by removing these unused functions.
The last user of dn_serial_console_write() was removed in v2.3.41.
The other functions never had any users.
