Merge tag 'asahi-soc-dt-5.17-v2' of https://github.com/AsahiLinux/linux into arm/dt

Apple SoC DT updates for 5.17, round 2:

- Various cleanups (removing useless props, sorting nodes, renaming
  things)
- Add PMGR min-state binding & props (see PMGR pull for driver change)
- Initial compatibles for t600x machines (M1 Pro/Max). This covers the
  bindings that just need compatible bumps & minor tweaks, no driver
  changes.
- Add watchdog node (driver not merged yet, hopefully will be; binding
  went in the previous pull)
- Add missing power-domains property to the mailbox binding
