arm: vf610: zii devel b: Add support for switch interrupts
The Switches use GPIO lines to indicate interrupts from two of the switches. With these interrupts in place, we can make use of the interrupt controllers within the switch to indicate when the internal PHYs generate an interrupt. Use standard PHY properties to do this.
