Subject: [PATCH 36/52] m68k: q40: Add and use "q40.h"

When building with W=1:

    arch/m68k/q40/q40ints.c:84:13: warning: no previous prototype for ‘q40_init_IRQ’ [-Wmissing-prototypes]
       84 | void __init q40_init_IRQ(void)
	  |             ^~~~~~~~~~~~
    arch/m68k/q40/q40ints.c:112:6: warning: no previous prototype for ‘q40_mksound’ [-Wmissing-prototypes]
      112 | void q40_mksound(unsigned int hz, unsigned int ticks)
	  |      ^~~~~~~~~~~
    arch/m68k/q40/q40ints.c:152:6: warning: no previous prototype for ‘q40_sched_init’ [-Wmissing-prototypes]
      152 | void q40_sched_init (void)
	  |      ^~~~~~~~~~~~~~

Fix this by introducing a new header file "q40.h" for holding the
prototypes of functions implemented in arch/m68k/q40/.
