Pull ACPI fixes from Rafael Wysocki:
 "These fix the ACPI initialization ordering on ARM and ACPI IRQ
  management in the cases when irq_create_fwspec_mapping() fails.

  Specifics:

   - Fix ACPI initialization ordering on ARM that was changed
     incorrectly during the 6.5 development cycle (Hanjun Guo)

   - Make acpi_register_gsi() return an error code as appropriate when
     irq_create_fwspec_mapping() returns 0 on failure (Sunil V L)"
