When building with W=1:
arch/m68k/mvme16x/config.c:208:6: warning: no previous prototype for ‘mvme16x_cons_write’ [-Wmissing-prototypes]
208 | void mvme16x_cons_write(struct console *co, const char *str, unsigned count)
| ^~~~~~~~~~~~~~~~~~
Fix this by introducing a new header file "mvme16x.h" for holding the
prototypes of functions implemented in arch/m68k/mvme16x/.
