It looks like CONFIG_IRQ_DOMAIN is getting selected by TWL4030_CORE.
Drivers must not select that config symbol. It looks like commit
da28adbd (mfd: twl-core: Add initial DT support for twl4030/twl6030)
is the culprit.
The following patch should solve the problem:
diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig
index 13c468e..e43a570 100644

Say yes here if you have TWL4030 / TWL6030 family chip on your board.
This core driver provides register access and IRQ handling
