Re: [PATCH v3 4/4] arm64: dts: apple: t8103: Add cd321x nodes

All M1 Mac devices have 2 SoC connected USB-C ports and use cd321x USB
type C port switch and power deliver controllers. I2c bus and adresses
configuration are for all devices equal.
The iMac (24-inch, 2021) has a configuration with 2 additional USB-C
ports (j456) using two addiotional cd321x controllers.
