nios2: introduce arch_zone_limits_init()
Move calculations of zone limits to a dedicated arch_zone_limits_init()
function.
Later MM core will use this function as an architecture specific callback
during nodes and zones initialization and thus there won't be a need to
call free_area_init() from every architecture.
