2012-05-08mmc: sdhci: add the quirk for broken r1b responseJaehoon Chung
When response type is R1b, mask value is added the SDHCI_INT_DAT_END. but in while(), didn't check that flag. So sdhci controller didn't work fine. CMD6 didn't always complete. So add the quirks for broken r1b response and add the timeout value to prevent the infinite loop.

2012-01-08mmc: Implement card detection.Thierry Reding
Check for card detect each time an MMC/SD device is initialized. If card detection is not implemented, this code behaves as before and continues assuming a card is present. If no card is detected, has_init is reset for the MMC/SD device (to force initialization next time) and an error is returned.
