Merge branch 'acpi-irqchip'

Merge irqchip changes related to ACPI support that are needed to enable
GICv5 IWB ACPI probe ordering detection on ARM, including the addition
of acpi_device_clear_deps() and RISC-V interrupt controller management
code refactoring to extract generic code from it into the common ACPI
IRQ code (Lorenzo Pieralisi)

* acpi-irqchip:
  irqchip/gic-v5: Enable GICv5 IWB ACPI probe ordering detection
  ACPI/IORT: Implement ACPI infrastructure to enable GICv5 IWB probe deferral
  ACPI: irq: Move RISC-V interrupt controllers autodep to ACPI IRQ code
  ACPI: RISC-V: Fix riscv_acpi_add_prt_dep() loop handling
  ACPI: RISC-V: Check acpi_get_handle() status in riscv_acpi_add_prt_dep()
  ACPI: RISC-V: Fix riscv_acpi_irq_get_dep() loop termination
  ACPI: Add acpi_device_clear_deps() helper function
