[PATCH 0/3] Switch Apple silicon boards to upstream device trees

The Linux device trees for Apple silicon devices cover now most of the
hardware as u-boot's internal device trees for M1 devices. Linux has in
addition device trees M2 and M1 and M2 Pro/Max/Ultra devices which were
never added in u-boot.
The most common use case for u-boot on Apple silicon devices does not
use DTBs from u-boot but passes runtime modified device trees from an
earlier boot loader (m1n1).
This change regresses support for the DWC3 based USB-C ports and the SPI
based keyboard on M1 and M1 Pro/Max notebooks. The regression for the
USB-C ports will be fixed when dts/upstream is synced to Linux v7.0.
The dt-bindings and device tree nodes for the SPI keyboard has still to
be submitted upstream.
These regression are in my opinion acceptable due to the limited use of
u-boot's DTBs for these targets.
