Because dfl.c uses the 'devm_ioremap', 'devm_iounmap',
'devm_ioremap_resource', and 'devm_platform_ioremap_resource'
functions, it should depend on HAS_IOMEM.
This fixes make allyesconfig under UML (ARCH=um), which doesn't provide
HAS_IOMEM.
Fixes: 89eb35e810a8 ("fpga: dfl: map feature mmio resources in their own feature drivers")

Applied to for-5.10,
I fixed up your commit message (dropped the drivers:)
