Merge tag 'pull-target-arm-20221216' of https://git.linaro.org/people/pmaydell/qemu-arm into staging

reset refactoring queue:
 * remove uses of qdev_reset_all(), qbus_reset_all(), device_legacy_reset()
 * convert various devices to 3-phase reset, so we can remove their
   uses of device_class_set_parent_reset()
