iommu: Introduce device_iommu_capable()
iommu_capable() only really works for systems where all IOMMU instances
are completely homogeneous, and all devices are IOMMU-mapped. Implement
the new variant which will be able to give a more accurate answer for
whichever device the caller is actually interested in, and even more so
once all the external users have been converted and we can reliably pass
the device pointer through the internal driver interface too.
