By taking GENERIC_IOREMAP method, the generic ioremap_prot() and iounmap() are visible and available to arch. This change will simplify implementation by removing duplicated code with generic ioremap_prot() and iounmap(), and has the equivalent functioality. For hexagon, the current ioremap() and iounmap() are the same as generic version. After taking GENERIC_IOREMAP way, the old ioremap() and iounmap() can be completely removed.
