Use the generic ioremap_prot and iounmap helpers.
Note that the io.h include in pgtable.h had to be removed to not create
an include loop. As far as I can tell there was no need for it to
start with.

All MMU-enabled ports have a non-trivial ioremap and should thus provide
the prototype for their implementation instead of providing a generic
one unless a different symbol is not defined. Note that this only
affects sparc32 nds32 as all others do provide their own version.
Also update the kerneldoc comments in asm-generic/io.h to explain the
situation around the default ioremap* implementations correctly.

mmiowb() only makes sense for SMP platforms, so we can remove it
entirely for nds32.

It broke the 'allmodconfig' build.
We need to include <linux/types.h> to make sure the type is defined
before using it.
