[PATCH] mm: include linux/pfn.h for PHYS_PFN definition

A change to asm-generic/memory_model.h caused a new build error
in some configurations:

mach-clps711x/common.c:39:10: error: implicit declaration of function 'PHYS_PFN'
.pfn = __phys_to_pfn(CLPS711X_PHYS_BASE),

This includes the linux/pfn.h header from the same file to avoid the
error.

I was listed as 'Cc' on the original patch, but don't see it in my inbox.

I can queue up the fixed version in the asm-generic tree if you like that,
otherwise please fold this fixup into the patch, or drop it if we want to
avoid the extra #include.
