Following patch caused this build break,

gpio: ixp4xx: Make irqchip immutable
[ Upstream commit 94e9bc73d85aa6ecfe249e985ff57abe0ab35f34 ]

This turns the IXP4xx GPIO irqchip into an immutable
irqchip, a bit different from the standard template due
to being hierarchical.

Tested on the IXP4xx which uses drivers/ata/pata_ixp4xx_cf.c
for a rootfs on compact flash with IRQs from this GPIO
block to the CF ATA controller.
