idmaengine: make FSL_EDMA and INTEL_IDMA64 depends on HAS_IOMEM
On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it could have a fully functional s390 kernel
with CONFIG_PCI=n, then the relevant iomem mapping functions
[including ioremap(), devm_ioremap(), etc.] are not available.
Here let FSL_EDMA and INTEL_IDMA64 depend on HAS_IOMEM so that it
won't be built to cause below compiling error if PCI is unset.
