[PATCH 6/8] mfd: Use interrupt-parent as IRQ controller if specified in DT

[Lee Jones <lee.jones@xxxxxxxxxx>]

Without this patch the default behaviour is to climb the Device
Tree and use the first encountered interrupt controller. This
does not take into account if a device node has specified to use
a particular IRQ controller using the interrupt-parent property.
This patch ensures that property is adhered to.
