The function scans for a descriptor that contains the queried address, and returns the respective findings for the first entry that is a hit. If no entry is found, it returns default attributes for -normal chacheable DRAM and the input address, hence telling the `MMU` code that the requested +normal cacheable DRAM and the input address, hence telling the `MMU` code that the requested address should be `identity mapped`. Due to this default behavior, it is not needed to define normal cacheable DRAM regions.
