x86, memblock: Use memblock_memory_size()/memblock_free_memory_size() to get correct dma_reserve
memblock_memory_size() will return memory size in memblock.memory.region.
memblock_free_memory_size() will return free memory size in memblock.memory.region.
So We can get exact reseved size in specified range.
Set the size right after initmem_init(), because later bootmem API will
get area above 16M. (except some fallback).
Later after we remove the bootmem, We could call that just before paging_init().
