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. Here, adding a new crossbar device node and replacing all the peripheral interrupt numbers with its fixed crossbar input lines.
