Subject[PATCH] PCI: Add dummy pci_irqd_intx_xlate() for CONFIG_PCI=n build
Date
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().
