PCI: endpoint: Use EPC's device in dma_alloc_coherent()/dma_free_coherent()
After commit 723288836628 ("of: restrict DMA configuration"),
of_dma_configure() doesn't configure the coherent_dma_mask/dma_mask
of endpoint function device (since it doesn't have a DT node associated
with and hence no dma-ranges property), resulting in
dma_alloc_coherent() (used in pci_epf_alloc_space()) to fail.
Fix it by making dma_alloc_coherent() use EPC's device for allocating
memory address.
