Now with dma_mask series merged and max*pfn has consistent meaning on ARM as rest of the arch's thanks to RMK's mega series, lets switch ARM code to NO_BOOTMEM. With NO_BOOTMEM change, now we use memblock allocator to reserve space for crash kernel to have one less dependency with nobootmem allocator wrapper. Tested with both flat memory and sparse (faked) memory models with highmem enabled.
