mm/memblock: Do some refactoring, enhance API
Refactor the memblock code and extend the memblock API to make it more flexible. With the extended API it is simple to define and work with additional memory lists. The static functions memblock_add_region and __memblock_remove are renamed to memblock_add_range and meblock_remove_range and added to the memblock API. The __next_free_mem_range and __next_free_mem_range_rev functions are replaced with calls to the more generic list walkers __next_mem_range and __next_mem_range_rev. To walk an arbitrary memory list two new macros for_each_mem_range and for_each_mem_range_rev are added. These new macros are used to define for_each_free_mem_range and for_each_free_mem_range_reverse.
