Sergei,

Why not "sdmmc" or "sdhci" or "sdio" then? It would be great to name
nodes in same way, but there is no exact requirement in ePAPR v1.1
regarding SD/MMC controllers. Also, in Linux I don't see that someone
strictly follows this requirement. This renaming will affect driver,
since .compatible strings likely also need changing.
