[ Upstream commit 96e0cbca1cb96e9d3deac3051aa816e13082f3fd ]

Until now, the SDIO quirks are applied directly from the driver.
However, it is better to apply the quirks before driver probing. So,
this patch relocate the quirks in the MMC framework.

Note that the WF200 has no valid SDIO VID/PID. Therefore, we match DT
rather than on the SDIO VID/PID.
