The changes in t8103.dtsi and t8112.dtsi conflict with my "Add Apple SPI
controller and spi-nor dt nodes" in
https://lore.kernel.org/asahi/20241102-asahi-spi-dt-v1-0-7ac44c0a88f9@jannau.net/

I think it makes more sense to add the spi controller nodes in one go
instead of piece by piece based on device support.
