That's a good question, other DTs do the same thing, I suspect the 
sd-vsel-gpios could be dropped, but as long as it is not outright 
harmful, it can be used for backward compatibility to support less 
complete OSes which may not handle the eSDHC VSELECT bit , so I figured 
it is good to keep both options.
