From: Jaehoon Chung <jh80.ch...@samsung.com>
If controller use SDHCI_QUIRK_BROKEN_CARD_DETECTION quirk,
controller need always polling detect
In this case, always generated interrupt.Because controller checked card status.
I think that is not efficiently.
But if card is nonremovable, we need not always polling.
So i added the check-point which is nonremovable or not
