Subject: [PATCH V2 3/7] ARM: DTS: DRA: Add crossbar device binding

This adds the irq crossbar device node.

There is a IRQ crossbar device in the soc, which
maps the irq requests from the peripherals to the
mpu interrupt controller's inputs. The Peripheral irq
requests are connected to only one crossbar
input and the output of the crossbar is connected to only one
controller's input line. The crossbar device is used to map
a peripheral input to a free mpu's interrupt controller line.
