hexagon: mm: convert to GENERIC_IOREMAP 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.

hexagon: use generic strncpy/strnlen from_user Remove the hexagon implementation of strncpy/strnlen and instead use the generic version. The hexagon version reads the data twice for strncpy() by doing an extra strnlen(), and it apparently lacks a check for user_addr_max().
