mmc: sdhci: add quirk for keeping card power during suspend
Add quirk SDHCI_QUIRK2_HOST_OFF_CARD_ON to cater for the case when the
card keeps power during suspend but the host controller does not i.e.
the card power is not controlled by the host controller. In that
case, the controller must be fully reset on resume.
