iommu/fsl_pamu: remove ->domain_window_enable
The only thing that fsl_pamu_window_enable does for the current caller
is to fill in the prot value in the only dma_window structure, and to
propagate a few values from the iommu_domain_geometry struture into the
dma_window. Remove the dma_window entirely, hardcode the prot value and
otherwise use the iommu_domain_geometry structure instead.
Remove the now unused ->domain_window_enable iommu method.
