regulator: tps65917/palmas: Simplify multiple dereference of ddata->palmas_matches[idx]
Converting dt to platform data logic involves picking up information that is unique per regulator, however we can improve readability of the code by dereferencing ddata->palmas_matches[idx] once in the loop. While at it fix reuse of generic palmas_matches common variable while reporting error for a specific regulator (which may be from 65917/palmas list).
