The admac bindinds don't have "iommus" or "power-domains". Fix in https://github.com/jannau/linux/commit/c9a0ff4581197064c560b05e2a6861d723a89... as preparation for Apple t600x (M1 Pro/Max/Ultra) devicetree patches.

I've have a fixed version of this patch in https://github.com/jannau/linux/commit/6ff76db8221d0f71cbacd9f6add58354350fc...
I was preparing the same change for t600x so it made sense to apply changes to this patch as well. Except for order and the wrong address all issue were discovered by `make dtbs_check`.
I plan to send https://github.com/jannau/linux/tree/apple-t600x-dts-for-v6.1 tomorrow.
ciao
