m68k/nommu: add missing definition of ARCH_PFN_OFFSET
Patch series "fixups for generic implementation of pfn_valid()".
Guenter reported boot failures on m68k-nommu and sh caused by the switch to
the generic implementation of pfn_valid():

These are small fixups that address the issues.
This patch (of 2):
On m68k/nommu RAM does not necessarily start at 0x0 and when it does not
pfn_valid() uses a wrong offset into the memory map which causes silent
boot failures.
Define ARCH_PFN_OFFSET to make pfn_valid() use the correct offset.
