Actually this patch is not correct. The MFD supplies IRQ lines without any
domain behind it, because of that the supplied list of IRQs is abstract to the
hardware and has no meaning in the Linux kernel. I dunno how it's supposed to
work (perhaps it involves the GIC driver hooks for IMX23/28 platforms).
