[PATCH] iio:adc:stm32-adc: Add HAS_IOMEM dependency

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

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.

Applied to the fixes-togreg branch of iio.git.

Thanks
