[ Upstream commit 8e2e4f3c58528c6040b5762b666734f8cceba568 ]
When CONFIG_HAS_IOMEM is not set/enabled, certain iomap() family functions [including ioremap(), devm_ioremap(), etc.] are not available. Drivers that use these functions should depend on HAS_IOMEM so that they do not cause build errors.
Mends this build error: s390-linux-ld: drivers/dma/sf-pdma/sf-pdma.o: in function `sf_pdma_probe': sf-pdma.c:(.text+0x1668): undefined reference to `devm_ioremap_resource'
