When building for the UM arch and neither INDIRECT_IOMEM=y, nor
HAS_IOMEM=y is selected, the build fails because the memcpy_fromio and
memcpy_toio functions are not defined. Fix it here by depending on
HAS_IOMEM or INDIRECT_IOMEM.

defines to overwrite the default. So, on s390 we always use the fast
zpci operations and don't fall back to the generic ones.

Remove the eieio() calls in _memcpy_fromio, to bring its implementation
closer to the one from lib/iomem_copy.c. These eieio() calls don't seem
to be necessary, because the _memcpy_toio completely omits them. Also
the legacy code from ppc was not doing them.
