arch, mm: set high_memory in free_area_init()
high_memory defines upper bound on the directly mapped memory. This bound is defined by the beginning of ZONE_HIGHMEM when a system has high memory and by the end of memory otherwise. All this is known to generic memory management initialization code that can set high_memory while initializing core mm structures. Add a generic calculation of high_memory to free_area_init() and remove per-architecture calculation except for the architectures that set and use high_memory earlier than that.
