iommu/fsl: Add the window permission flag as a parameter to iommu_window_enable API.
Each iommu window can have access permissions associated with it. Extended the window_enable API to incorporate window access permissions. In case of PAMU each window can have its specific set of permissions. Signed-off-by: Varun Sethi <Varun.Sethi@freescale.com> Signed-off-by: Joerg Roedel <joro@8bytes.org>
