Subject: genirq: Generic irq chip requires IRQ_DOMAIN

commit 923fa4ea382f592dee2ba3b205befb90cbddf3af upstream.

The generic_chip.c uses interfaces from irq_domain.c which is
controlled by the IRQ_DOMAIN config option, but there is no Kconfig
dependency so the build can fail:

linux/kernel/irq/generic-chip.c:400:11: error:
'irq_domain_xlate_onetwocell' undeclared here (not in a function)

Select IRQ_DOMAIN when GENERIC_IRQ_CHIP is selected.
