Merge tag 'pull-target-arm-20230216' of https://git.linaro.org/people/pmaydell/qemu-arm into staging

target-arm queue:
 * Some mostly M-profile-related code cleanups
 * avocado: Retire the boot_linux.py AArch64 TCG tests
 * hw/arm/smmuv3: Add GBPA register
 * arm/virt: don't try to spell out the accelerator
 * hw/arm: Attach PSPI module to NPCM7XX SoC
 * Some cleanup/refactoring patches aiming towards
   allowing building Arm targets without CONFIG_TCG
