[PATCH 17/52] m68k: amiga: Add and use "amiga.h"

arch/m68k/amiga/amisound.c:48:13: warning: no previous prototype for ‘amiga_init_sound’ [-Wmissing-prototypes]
48 | void __init amiga_init_sound(void)
| ^~~~~~~~~~~~~~~~
arch/m68k/amiga/amisound.c:71:6: warning: no previous prototype for ‘amiga_mksound’ [-Wmissing-prototypes]
71 | void amiga_mksound( unsigned int hz, unsigned int ticks )
| ^~~~~~~~~~~~~

Fix this by introducing a new header file "amiga.h" for holding the
prototypes of functions implemented in arch/m68k/amiga/.
