iommu_ops are not supposed to change at runtime.
Functions 'iommu_device_set_ops' and 'bus_set_iommu' working with
const iommu_ops provided by <linux/iommu.h>. So mark the non-const
structs as const.

This doesn't apply cleanly to the arm/mediatek branch in the iommu-tree.
Please rebase it against that branch and update the subject to:
iommu/mediatek: Constify iommu_ops
to match the convention used in the iommu-tree and send it again.
Thanks,
Joerg
