I'm not sure that this option is needed. Some cards I/O errors can be 
avoided by increasing timeout and has no negative influence on other 
cards read/write operations performance.
Moreover there are a lot of timeout values defined in sdhci and mmc 
drivers, so why should I put at config just only one? Maybe the simplest 
solution is to leave at this code only 200 ms value.
What do you think?
