arch, drivers: replace for_each_membock() with for_each_mem_range()
There are several occurrences of the following pattern:
for_each_memblock(memory, reg) {
start = __pfn_to_phys(memblock_region_memory_base_pfn(reg);
end = __pfn_to_phys(memblock_region_memory_end_pfn(reg));
/* do something with start and end */
}
Using for_each_mem_range() iterator is more appropriate in such cases and
allows simpler and cleaner code.
