Geert Uytterhoeven b66f55cdba m68knommu: Add missing initialization of max_pfn and {min,max}_low_pfn ...

If max_pfn is not initialized, the block layer may use wrong DMA masks.

Replace open-coded shifts by PFN_DOWN(), and drop the "0 on coldfire"
comment, as it is not even true on all Coldfires, let alone all
m68knommu platforms.
