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>.
