PCI: endpoint: pci-epf-vntb: Implement .get_dma_dev()
When vNTB is used as a PCI endpoint function, the NTB device is backed
by a virtual PCI function. For DMA API allocations and mappings, NTB
clients must use the device that is associated with the IOMMU domain.
Implement ntb_dev_ops->get_dma_dev() for pci-epf-vntb and return the EPC
parent device.
