PCI: generic: Select IRQ_DOMAIN 

The generic PCI host controller calls of_irq_parse_and_map_pci() in its IRQ
fixup, but that function is only available when CONFIG_IRQ_DOMAIN is set:

  drivers/pci/built-in.o: In function `pci_host_common_probe':
  drivers/pci/host/pci-host-common.c:181: undefined reference to `of_irq_parse_and_map_pci'

There is no downside in enabling the domains here, so use a Kconfig
select statement to ensure it's always available to this driver.

Say Y here if you want to support a simple generic PCI host
controller, such as the one emulated by kvmtool.
