x86: use optimized ioresource lookup in ioremap function
Use the optimized ioresource lookup, "region_is_ram", for the ioremap function. If the region is not found, it falls back to the "page_is_ram" function. If it is found and it is RAM, then the usual warning message is issued, and the ioremap operation is aborted. Otherwise, the ioremap operation continues.
