-mx25 touchscreen conversion queue module which controls the ADC unit of the

-Required properties:
- - compatible: Should be "fsl,imx25-tcq".
- - reg: Memory range of the device.
- - interrupts: Should be the interrupt number associated with this module within
-   the tscadc unit (<0>).
- - fsl,wires: Should be '<4>' or '<5>'

Linux-next is broken as the MFD binding has been picked up without this 
one, so I've applied it.
