ARM: dts: TS-4800: add FPGA's IRQ controller support
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. Signed-off-by: Damien Riegel <damien.riegel@savoirfairelinux.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
