memblock, x86: Reimplement memblock_find_dma_reserve() using iterators
memblock_find_dma_reserve() wants to find out how much memory is reserved under MAX_DMA_PFN. memblock_x86_memory_[free_]in_range() are used to find out the amounts of all available and free memory in the area, which are then subtracted to find out the amount of reservation. memblock_x86_memblock_[free_]in_range() are implemented using __memblock_x86_memory_in_range() which builds ranges from memblock and then count them, which is rather unnecessarily complex. This patch open codes the counting logic directly in memblock_find_dma_reserve() using memblock iterators and removes now unused __memblock_x86_memory_in_range() and find_range_array().
