m68k: Pass a pointer to virt_to_pfn() virt_to_page()
Functions that work on a pointer to virtual memory such as
virt_to_pfn() and users of that function such as
virt_to_page() are supposed to pass a pointer to virtual
memory, ideally a (void *) or other pointer. However since
many architectures implement virt_to_pfn() as a macro,
this function becomes polymorphic and accepts both a
(unsigned long) and a (void *).
Fix up the offending calls in arch/m68k with explicit casts.
The page table include <asm/pgtable.h> will include different
variants of the defines depending on whether you build for
classic m68k, ColdFire or Sun3, so fix all variants.
Delete Coldfire pte_pagenr() which was using unsigned long
semantics from __pte_page().
