powerpc/mm: Fix compile error of pgtable-ppc64.h
It seems that forward declaration couldn't work well with typedef, use
struct spinlock directly to avoiding following build errors:

include/linux/spinlock_types.h:76: error: redefinition of typedef 'spinlock_t'
/root/linux-next/arch/powerpc/include/asm/pgtable-ppc64.h:563: note: previous declaration of 'spinlock_t' was here
