From: Jerry Huang
Add callback function sdhci_get_cd to detect the card.
And one new callback added to implement the card detect in sdhci struncture.
If special platform has the card detect callback, it will return the card
state, the value zero is for absent cardi and one is for present card.

Add callback function sdhci_get_cd to detect the card.
And one new callback added to implement the card detect in sdhci struncture.
