PCI: rcar: Select PCI_MSI_IRQ_DOMAIN
The R-Car PCIe driver requires the use of IRQ domains for its MSI code: drivers/pci/host/pcie-rcar.c:635:9: error: implicit declaration of function 'irq_find_mapping' [-Werror=implicit-function-declaration] drivers/pci/host/pcie-rcar.c:666:8: error: implicit declaration of function 'irq_create_mapping' [-Werror=implicit-function-declaration] ... Add a Kconfig select to ensure that the feature is always enabled. This is not consistent with what the other drivers do at the moment, but I have another patch that changes them to do it like this one, which is more logical.
