Janne Grunau a1a47eee67 arm: apple: Add Apple M3 (t8122) support
Apple's M3 SoC is similar to M1 and M2 but uses a different memory map.
The main difference is that RAM starts at 0x100_0000_0000 like on t600x
and t602x (M1 and M2 Pro/Max/Ultra). Otherwise IO blocks have been
rearranged.
U-boot's existing drivers are compatible with the hardware and M3 device
trees will carry "apple,t8103-*" compatible strings. Only
apple-atcphy-reset might need a new compatible due to USB4 / DisplayPort
changes the Linux driver has to deal with.
