m68k: Provide __phys_to_pfn() and __pfn_to_phys()

The defconfig build of m68k was failing with the error:
implicit declaration of function '__pfn_to_phys'

Other architectures have added <asm/memory.h>, but if we do so here then
we will also get redeclaration of some other functions. So it is better
to copy these macros into page.h.
