Enable FPGA's IRQ controller. It is in charge of dispatching interrupts
generated by IPs in the FPGA. The SoC is notified that an interrupt
occurred through a GPIO.

This enables support for the CAN controller located in the FPGA.

Please use hyphen rather than underscore in node name. Also
why do we need '0,' in unit-address?

For nodes under bus node with unit-address (or 'reg' property), it makes
more sense to sort the nodes in order of unit-address.
