Stack power pins for the TPS62130?

Uli Köhler requested to merge ulikoehler/kicad-symbols:TPS62130 into master

This merge request is intended to discuss if we should stack the power pins for the TPS62130. Datasheet

a) Stack PGND, AGND & EP. Justification: Datasheet says Power Ground. Must be connected directly to the Exposed Thermal Pad and common ground plane. b) Stack PVIN & AVIN. Justification: Datasheet says Supply voltage for control circuitry. Connect to the same source as PVIN..

There is slight incompatibility introduced reagarding the PIN pins. Users connecting both PIN pins separately and updating the symbol will possibly face unconnected. This cannot happen for the GND pins, since the EP is at the same position as the newly stacked GND pins.

The same compatibility caveats apply for the derived parts.

We could possibly downsize the symbol, but that would introduce major incompatibility. I dont think that's worth it.
