Fix Winbond W29EE011, W29EE012, W29C010M, W29C011A probing

Browse Source 
According to the datasheets probe_w29ee011 is the only valid probe
function for those chips, but we have reports where those chips
were only detected with probe_jedec, and thus we assume that our
datasheets only cover an earlier stepping.

Corresponding to flashrom svn r1391.
