to be able to do raw writes was very usefull for me to reproduce a bug in the
UBI layer in the past. Bitflips happen very rarely but they happen, and with
this code you are able to force this and see how other SW layer handle this. Due
to the fact there was an empty implementation in the u-boot code for this I
thought it might be usefull for others too.
