m68k: mm: Move paging_init() to common <asm/pgtable.h> 

When building with W=1:

    arch/m68k/mm/motorola.c:414:13: warning: no previous prototype for ‘paging_init’ [-Wmissing-prototypes]
      414 | void __init paging_init(void)
	  |             ^~~~~~~~~~~
    arch/m68k/mm/sun3mmu.c:36:13: warning: no previous prototype for ‘paging_init’ [-Wmissing-prototypes]
       36 | void __init paging_init(void)
	  |             ^~~~~~~~~~~

Fix this by consolidating the multiple prototypes into the common
<asm/pgtable.h>.
