iommu: Pass struct iommu_iotlb_gather to ->unmap() and ->iotlb_sync()
To allow IOMMU drivers to batch up TLB flushing operations and postpone them until ->iotlb_sync() is called, extend the prototypes for the ->unmap() and ->iotlb_sync() IOMMU ops callbacks to take a pointer to the current iommu_iotlb_gather structure. All affected IOMMU drivers are updated, but there should be no functional change since the extra parameter is ignored for now. Signed-off-by: Will Deacon <will@kernel.org>
