mmc: sdhci-of-esdhc: enable interrupt mode to detect card
Enable interrupt mode to detect card instead of polling mode for P1020/P4080/P5020/P5040/T1040 by removing the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION. This could improve data transferring performance and avoid the call trace caused by polling card status sometime.
