WCD9335 supports two lines of irqs INTR1 and INTR2.
Multiple interrupts are muxed via these lines.
INTR1 consists of all possible interrupt sources like:
Ear OCP, HPH OCP, MBHC, MAD, VBAT, and SVA
INTR2 is a subset of first interrupt sources like MAD, VBAT, and SVA

I'm confused why these are defined here. The binding for the wc9335 is
not an interrupt-controller.
I can move this defines to include/linux/mfd/wcd9335/wcd9335.h as there 
are no active users for this, but I  was hoping that these can be used 
in DT in future.

WCD9335 is an interrupt controller too. It muxes multiple interrupts via 
a gpio line interrupt.

I did mention this in the bindings.

+- interrupt-controller:
+	Usage: required
+	Definition: Indicating that this is a interrupt controller
+
+- #interrupt-cells:
+	Usage: required
+	Value type: <int>
+	Definition: should be 1
