[PATCH v2 1/2] ARM: dts: TS-4800: add FPGA's IRQ controller support

[Damien Riegel]

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.

Changes in v2:
 - Remove new lines
 - Use hyphen rather than underscore in node name
 - Get rid of "0," in unit-address
 - Move node to keep them sorted by unit-address

Applied both, thanks.
