Pull irqchip updates from Marc Zyngier:
- Second batch of the GICv4.1 support saga
- Level triggered interrupt support for the stm32 controller
- Versatile-fpga chained interrupt fixes
- DT support for cascaded VIC interrupt controller
- RPi irqchip initialization fixes
- Multi-instance support for the Xilinx interrupt controller
- Multi-instance support for the PLIC interrupt controller
- CPU hotplug support for the PLIC interrupt controller
- Ingenic X1000 TCU support
- Small fixes all over the shop (GICv3, GICv4, Xilinx, Atmel, sa1111)
- Cleanups (setup_irq removal, zero-length array removal)
