s390: 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.
Here, add wrapper functions ioremap_prot() and iounmap() for s390's
special operation when ioremap() and iounmap().
And also replace including <asm-generic/io.h> with <asm/io.h> in
arch/s390/kernel/perf_cpum_sf.c, otherwise building error will be seen
because macro defined in <asm/io.h> can't be seen in perf_cpum_sf.c.
