Apple SoC DT updates for 5.17, round 2:

Browse source 
- 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
