iommu: Restore iommu_flush_iotlb_all()

Browse source

This patch restores the iommu_flush_iotlb_all() function.
Commit

	69e5a17511 ("iommu: Remove useless flush from iommu_create_device_direct_mappings()")

claims it removed the last call-site, except it did not. There is still
at least one caller in

	drivers/gpu/drm/msm/msm_iommu.c

so keep the function around until all call-sites are updated.
