While I was testing the other quirk, I tested this one on 25, 35 & 51, but I 
can't trigger the bug on any of these CPU (without the quirk : the bug suppose 
there is an error reading one block and that the MMC layer then sends CMD12 
which can't stop the AHB transfer and thus the controler stays blocked. As I 
didn't met an error to read a block, I wasn't able to trigger the bug.
