Fix the compile time warning:
arch/m68k/68000/dragen2.c:38:13: warning: no previous prototype for 'init_dragen2' [-Wmissing-prototypes]
38 | void __init init_dragen2(char *command, int size)
| ^~~~~~~~~~~~
There already exists a header file prototype, but that file was not
included in the dragen2.c code.
