Since commit 4670d610d5923 ("PCI: Move OF-related PCI functions into
PCI core"), sparc:allmodconfig fails to build with the following error.
pcie-cadence-host.c:(.text+0x4c4):
undefined reference to `of_irq_parse_and_map_pci'
pcie-cadence-host.c:(.text+0x4c8):
undefined reference to `of_irq_parse_and_map_pci'
of_irq_parse_and_map_pci is now only available if OF_IRQ is enabled.
Make its declaration and its dummy function dependent on OF_IRQ
to solve the problem.
Fixes: 4670d610d5923 ("PCI: Move OF-related PCI functions into PCI core")
