msm: Add support for parsing domain info from dt

Add support for defining domains in device tree. A domain is a
collection of iommu context banks that share the same page table.
At boot the domains are created and assigned to an iommu_group.
An iommu_group is created for each domain with the context banks
added to the iommu_group.
