plankton: fix charging voltage selection
Fix for plankton v2 so that the VBUS voltage selection buttons
work properly (5V, 12V, and 20V).
BUG=none
BRANCH=none
TEST=load onto plankton v2, connect type-C to samus, and press
5V, 12V, and 20V buttons. read adc on samus side to verify it
is getting the proper voltage.
