s390/iommu: get rid of S390_CCW_IOMMU and S390_AP_IOMMU
These don't do anything anymore, the only user of the symbol was
VFIO_CCW/AP which already "depends on VFIO" and VFIO itself selects
IOMMU_API.
When this was added VFIO was wrongly doing "depends on IOMMU_API" which
required some contortions like this to ensure IOMMU_API was turned on.
