I was under the impression that it can be defined inside the if statement 
since "make dt_binding_check" ran without any errors. If that's wrong, I'm not 
sure how else to make the property valid only for ist3032c (the two devices 
using ist3038c, samsung-j5 and j5x seem to have tm2-touchkey instead).
