Things should be ready to flip the remaining SoCs to use sdhci so we
should do that.
The only thing I'm aware of is that sdhci will try to keep probing
also mmc instances that are not wired. So some board specific dts files
may need to set some mmc instances with status = "disabled". Or maybe
the sdhci driver can be configured to stop trying after some timeout.
