Octopus: add reset logic for C0 TCPC
This change adds a call to the C0 TCPC reset for standalone TCPC boards
which have that pin hooked up in hardware, and adds the GPIO as
unimplemented for boards which do not have this yet.
BRANCH=None
BUG=b:112756630
TEST=Added a log print and rebooted EC on bobba to verify TCPC C0 reset,
then verified that charging on C0 worked. Also imaged yorp proto 2 and
rebooted, verifying C0 reset was not attempted.
