openrisc: mm: convert to GENERIC_IOREMAP
By taking GENERIC_IOREMAP method, the generic generic_ioremap_prot(), generic_iounmap(), and their generic wrapper ioremap_prot(), ioremap() and iounmap() are all visible and available to arch. Arch needs to provide wrapper functions to override the generic versions if there's arch specific handling in its ioremap_prot(), ioremap() or iounmap(). This change will simplify implementation by removing duplicated code with generic_ioremap_prot() and generic_iounmap(), and has the equivalent functioality as before. For openrisc, 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.
