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

Apple SoC DT updates for 5.17:

- Separate DTs for all t8103 platforms
- Add i2c and cd321x nodes
- Bindings for apple,wdt
- PMGR bindings and DT updates to instantiate it
- WiFi MAC address DT handling

This also includes the MAINTAINERS change for the PMGR driver itself, to
avoid merge issues; the driver will be sent in a different pull.

Manual fixups: Added i2c power domain references to the PMGR DT commit,
since a prior commit added the i2c nodes.
