From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

commit 121875b28e3bd7519a675bf8ea2c2e793452c2bd upstream.

Seems that there are config combinations in which this driver gets enabled
and hence selects the MFD, but with out HAS_IOMEM getting pulled in
via some other route. MFD is entirely contained in an
if HAS_IOMEM block, leading to the build issue in this bugzilla.
