mmc: add MMC_QUIRK_DISABLE_CD
006ebd5d introduced sdio_disable_cd(), which disconnects the pull-up resistor on CD/DAT[3] (pin 1) of the card. Make it possible to start using sdio_disable_cd() by introducing MMC_QUIRK_DISABLE_CD. Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com> Signed-off-by: Chris Ball <cjb@laptop.org>
