You're not specifying which config option you have enabled that selects
CONFIG_GENERIC_IRQ_CHIP and does not select CONFIG_IRQ_DOMAIN, but it does
look like there is a dependency here.

So, if this dependency is reasonable, it begs the question of why we have
CONFIG_GENERIC_IRQ_CHIP at all and shouldn't just make generic-chip.c
depend on CONFIG_IRQ_DOMAIN.
