Subject: [PATCH v2 09/52] m68k: kernel: Add and use "traps.h"

When building with W=1:

    arch/m68k/kernel/traps.c:754:17: warning: no previous prototype for ‘buserr_c’ [-Wmissing-prototypes]
      754 | asmlinkage void buserr_c(struct frame *fp)

    arch/m68k/kernel/traps.c:1140:17: warning: no previous prototype for ‘set_esp0’ [-Wmissing-prototypes]
     1140 | asmlinkage void set_esp0(unsigned long ssp)
	  |                 ^~~~~~~~
    arch/m68k/kernel/traps.c:1155:17: warning: no previous prototype for ‘fpemu_signal’ [-Wmissing-prototypes]
     1155 | asmlinkage void fpemu_signal(int signal, int code, void *addr)
	  |                 ^~~~~~~~~~~~
    arch/m68k/kernel/traps.c:1149:17: warning: no previous prototype for ‘fpsp040_die’ [-Wmissing-prototypes]
     1149 | asmlinkage void fpsp040_die(void)
	  |                 ^~~~~~~~~~~

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