Currently host drivers using the sdhci-pltfm code can not configure the
host based on the type of card inserted.

The sdio driver e.g. calls the card_init callback, so the host can now
know what card is used and configure itself accordingly.

Provide a callback for users of the sdhci-pltfm code to use this callback
function.
