[PATCH] m68k: pgtable: Add missing #include <asm/page.h>

[Geert Uytterhoeven]

When just including <linux/pgtable.h>:

    include/asm-generic/pgtable-nop4d.h:9:18: error: unknown type name ‘pgd_t’
	9 | typedef struct { pgd_t pgd; } p4d_t;
	  |                  ^~~~~

Make <asm/pgtable.h> self-contained by including <asm/page.h>.

Closes: https://lore.kernel.org/r/878r2uxwha.fsf@intel.com

Jani: Feel free to pick this up as a dependency.
Else I will queue this in the m68k tree for v6.10.
