irq/s390: Add arch_is_isolated_msi() for s390
s390 doesn't use irq_domains, so it has no place to set
IRQ_DOMAIN_FLAG_ISOLATED_MSI. Instead of continuing to abuse the iommu
subsystem to convey this information add a simple define which s390 can
make statically true. The define will cause msi_device_has_isolated() to
return true.
Remove IOMMU_CAP_INTR_REMAP from the s390 iommu driver.
