If CONFIG_PCI=n and CONFIG_PCI_DRA7XX_EP=y, the build fails with:
drivers/pci/dwc/pci-dra7xx.c:229:11: error: 'pci_irqd_intx_xlate' undeclared here (not in a function)
When building drivers/pci/dwc/pci-dra7xx.c without CONFIG_PCI, gcc is usually smart enough to realize that RC specific code is unreachable and can thus be eliminated.
However, gcc cannot do this if there is a function that isn't even declared.
Hence fix the issue by introducing a dummy for pci_irqd_intx_xlate().
