iommu/fsl: Add additional iommu attributes required by the PAMU driver.
Added the following domain attributes for the FSL PAMU driver: 1. Added new iommu stash attribute, which allows setting of the LIODN specific stash id parameter through IOMMU API. 2. Added an attribute for enabling/disabling DMA to a particular memory window. 3. Added domain attribute to check for PAMUV1 specific constraints.
