[PATCH] lib: fwts_ioport: add dummy stubs for non-x86 arch

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Architectures like PowerPC get a failure to build because we don't
have sys/io.h.  Since the I/O access is for just for x86 fwts tests
the easiest way forward is to implement dummy I/O funcs for non-x86
systems and don't include sys/io.h for these.
