m68k: amiga: Add and use "amiga.h"

When building with W=1:

    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/.
