drm/tegra: Use iommu_paging_domain_alloc()
Commit <17de3f5fdd35> ("iommu: Retire bus ops") removes iommu ops from
the bus structure. The iommu subsystem no longer relies on bus for
operations. So iommu_domain_alloc() interface is no longer relevant.
Replace iommu_domain_alloc() with iommu_paging_domain_alloc() which takes
the physical device from which the host1x_device virtual device was
instantiated. This physical device is a common parent to all physical
devices that are part of the virtual device.
