mm: implement for_each_valid_pfn() for CONFIG_FLATMEM
In the FLATMEM case, the default pfn_valid() just checks that the PFN is
within the range [ ARCH_PFN_OFFSET .. ARCH_PFN_OFFSET + max_mapnr ).
The for_each_valid_pfn() function can therefore be a simple for() loop
using those as min/max respectively.
