MMC subsystem provides a way to apply quirks when a device match some properties (VID, PID, etc...) Unfortunately, some SDIO devices do not comply with the SDIO specification and does not provide reliable VID/PID (eg. Silabs WF200). So, the drivers for these devices rely on device tree to identify the device. This patch allows the MMC to also rely on the device tree to apply a quirk.
