Merge tag 'irqchip-fixes-6.4-1' of git:// into irq/urgent

Pull irqchip fixes from Marc Zyngier:

  - MIPS GIC fixes for issues that could result in either
    loss of state in the interrupt controller, or a deadlock

  - Workaround for Mediatek Chromebooks that only save/restore
    partial state when turning the GIC redistributors off,
    resulting if fireworks if Linux uses interrupt priorities
    for pseudo-NMIs

  - Fix the MBIGEN error handling on init

  - Mark meson-gpio OF data structures as __maybe_unused,
    avoiding compilation warnings on non-OF setups
