libc/sysdeps/linux/arm/ioperm.c on trunk fails to compile for me because
of no declaration of ioperm at the point where libc_hidden_proto(ioperm)
requires one.  Including <sys/io.h> to get the declaration then shows up
that various types are inconsistent with that header; this patch fixes
things so that file compiles.
