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

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

Thanks, I'd like to pick this up as a dependency, so I can proceed with
my series. It'll also be queued for v6.10 via the drm subsystem.

Replying here too, I've merged this via drm-misc-next as d1815393cac0
("m68k: pgtable: Add missing #include <asm/page.h>").

Thanks for the patch!

Jani.
