iommu/fsl_pamu: remove support for multiple windows

Browse Source 
The only domains allocated forces use of a single window.  Remove all
the code related to multiple window support, as well as the need for
qman_portal to force a single window.

Remove the now unused DOMAIN_ATTR_WINDOWS iommu_attr.
