Mike Rapoport fa3354e4ea mm: free_area_init: use maximal zone PFNs rather than zone sizes ...

Currently, architectures that use free_area_init() to initialize memory
map and node and zone structures need to calculate zone and hole sizes.
We can use free_area_init_nodes() instead and let it detect the zone
boundaries while the architectures will only have to supply the possible
limits for the zones.
