Pull interrupt updates from Thomas Gleixner:
 "Core code:

   - Provide generic_handle_irq_safe() which can be invoked from any
     context (hard interrupt or threaded). This allows to remove ugly
     workarounds in drivers all over the place.

   - Use generic_handle_irq_safe() in the affected drivers.

   - The usual cleanups and improvements.

  Interrupt chip drivers:

   - Support for new interrupt chips or not yet supported variants:
     STM32MP14, Meson GPIO, Apple M1 PMU, Apple M1 AICv2, Qualcomm MPM

   - Convert the Xilinx driver to generic interrupt domains

   - Cleanup the irq_chip::name handling

   - The usual cleanups and improvements all over the place"
