In the current patch, these quirks are applied only if the device appears
in the device tree (see the condition above). If I implement them in
drivers/mmc/core/quirks.h they will be applied as soon as the device is
detected. Is it what we want?
Note: we already have had a discussion about the strange VID/PID declared
by this device:

It seems we already have had this discussion:
