Subject: [PATCH] irq: fix a Kconfig dependency

From: Nitin A Kamble <nitin.a.kamble@...el.com>

The generic_chip.c uses interfaces from irq_domain.c which is controlled by
the IRQ_DOMAIN config option.

Add a select statement in the Kconfig to reflect this requirement.

Without this fix, the generic_chip.c compilation fails like this:

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