Mark any SDHCI controllers that aren't registered by the board files as disabled in the device-tree files. In practice, these controllers: * Have nothing hooked up to them at all, or * For ports intended for SDIO usage, the drivers for anything that might be attached are not in the device-tree yet. If/when drivers appear, the SD/MMC port can be re-enabled. The only possible exception is TrimSlice's mico SD slot, but that wasn't enabled in the board files before anyway, and doesn't work when all the SDHCI controllers are enabled anyway.
