Pull irq chip driver updates from Thomas Gleixner:
 "Updates for interrupt chip drivers:

   - Remove the futile attempts to cleanup resources when the probing of
     the main interrupt chip fails for SiFIVE/PLIC devices. If that
     probe fails the system will stall immediately afterwards in the
     boot process without reaching a state where the error could be
     diagnosed. The lack of resource cleanup led to a frenzy of AI
     detected/assisted "fixes" which just make the code pretend to be
     correct for no value.

     Remove the existing half baked cleanup and immediately panic the
     machine when the probe fails. That's far more useful than letting
     it proceed and stall out a millisecond later with no information
     about the root cause.

   - A series of fixes for the ARM GIC-V3 driver addressing a potential
     double free, a bitmask overrun on 32-bit ARM and a OF node leak.

   - Automatically set the IRQ_DOMAIN_FLAG_DESTROY_GC when a interrupt
     domain is created that also allocates the generic interrupt chip
     during domain creation. That removes the requirement for manually
     setting the flag in the domain creation info structure when it
     contains a valid entry for allocating the generic interrupt chip.
     Remove the therefore redundant setters of
     IRQ_DOMAIN_FLAG_DESTROY_GC in the existing drivers.

   - Add support for Annapurna Labs FIC version 2 and 3 and implement
     affinity control for the demultiplexed interrupts by utilizing the
     recently merged interrupt redirection infrastructure.

   - Convert the ACPI device ID structures to named initializers

   - Consolidate the IPI related constants for RISC-V interrupt
     controllers

   - Add support for Qualcomm Purwa SoC interrupt chip and consolidate
     the workaround for the previous version in Hamoa SoCs.

   - The usual small fixes and improvements all over the place"
