dmaengine: SF_PDMA depends on HAS_IOMEM
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'
