mfd/ab8500-core: use irq_domain_add_simple()

From: Linus Walleij <[email protected]>

To be able to use SPARSE_IRQ while yet not using device tree, we need to use irq_domain_add_simple() that will allocate descriptors for the IRQs in the non-DT case, and fall back to using the linear irqdomain in the DT case.

Sam, requesting you ACK on this patch so we can merge them all together.
Lee, requesting your testing with Device Tree to see that this actually can fly as I wanted it.

Hi Linus,

In case it's not too late:

Cheers,

Too late for my pull request to ARM SoC, but the important thing is that the ARM SoC people see that you're OK with it so they can pull in my patches :-)

Thanks Sam!

Yours,
Linus Walleij
