Subject: [PATCH 0/2] Add DTs for all Apple M1 (t8103) devices

this series adds DTs for all current Apple M1 devices.
Specifically it adds DTs for following devices:
- MacBook Air (M1, 2020)
- Macbook Pro (13-inch, M1, 2020)
- iMac (24-inch, M1, 2021)

With the addition of PCIe support the devices started to differ in
their supported hardware. The MacBook Air and Pro do not have an
ethernet and USB PCIe controllers. The 24-inch iMac has a configuration
without USB ihost controller.

In addtion it will help with AsahiLinux bootloader (m1n1). It started
in October to refuse to load DTs that do not match the model it is
running on.
