We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.

I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.
