zinger: minimuffin: add board support for minimuffin
Minimuffin is identical to zinger, same MCU, same gpio, same
circuitry aroundt the MCU with two differences:
- Rated current is 2.25A instead of 3A
- USB PD hardware device ID needs to be different so that host
can differentiate between the two.
Due to the similarity between the two, minimuffin is defined
as a symlink to the zinger board.
BUG=none
BRANCH=samus
TEST=make BOARD=minimuffin
load onto a zinger and verify that samus reads device ID correctly
and limits input current limit to 2.25mA.
