powerpc/iommu: Remove iommu_del_device()
Now that power calls iommu_device_register() and populates its groups
using iommu_ops->device_group it should not be calling
iommu_group_remove_device().
The core code owns the groups and all the other related iommu data, it
will clean it up automatically.
Remove the bus notifiers and explicit calls to
iommu_group_remove_device().
Fixes: a940904443e4 ("powerpc/iommu: Add iommu_ops to report capabilities and allow blocking domains")
