My full expectation in v0 was that (most) everything in
soc dtsi would have been disabled by default.
As per 6.7-rc7 k3-am64-main.dtsi did not disable sdhci nodes,
so this was fine, I had even removed my unnecessary
status = okay since v1 :(
(Now I can see how you spotted it, thanks!)

Will re-add them just for sdhci nodes in v5.
