mmc: sdhci-esdhc-imx: fix cd regression for dt platform
Current card detect probe process is that when driver finds a valid ESDHC_CD_GPIO, it will clear the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION which is set by default for all esdhc/usdhc controllers. Then host driver will know there's a valid card detect function. Commit 8d86e4fc ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()") breaks GPIO CD function for dt platform that it will return directly when find ESDHC_CD_GPIO for dt platform which result in the later wrongly to keep SDHCI_QUIRK_BROKEN_CARD_DETECTION for all dt platforms. Then MMC_CAP_NEEDS_POLL will be used instead even there's a valid GPIO card detect. This patch adds back this function and follows the original approach to clear the quirk if find an valid CD GPIO for dt platforms.
