arm64: dts: apple: Add J474s, J475c and J475d device trees

Browse Source 
Add device trees for the M2 Pro Mac mini and the M2 Max and Ultra
Mac Studio. These devices are very similar to the M1 Max and Ultra
Mac Studio so reuse the device template, include the .dtsi for the new
SoCs and correct for the minimal differences.
