[Sasha Levin]

From: shirley her <shirley.her@xxxxxxxxxxxxxx>

[ Upstream commit cdd2b769789ae1a030e1a26f6c37c5833cabcb34 ]

To fix support for the O2 host controller Seabird1, set the quirk
SDHCI_QUIRK2_PRESET_VALUE_BROKEN and the capability bit MMC_CAP2_NO_SDIO.
Moreover, assign the ->get_cd() callback.
