Add preliminary device trees for the Apple M1 mini (2020) and
Apple M1 Macbook Pro 13" (2020). Device tree bindings for
the Apple M1 SoC are still being formalized and these device
trees will be synchronized with the Linux kernel as needed.
These device trees are provided as a reference only as U-Boot
uses the device tree passed by the m1n1 bootloader.
