TCPMv2: Don't reset power supply when toggling

When manually toggling, the power supply doesn't need to be reset
constantly.  Instead, reset the power supply when RD super state is
entered from any other state besides unattached_src.

BRANCH=None
BUG=None
TEST=on waddledee, host command prints related to the
PD_EVENT_POWER_CHANGE spamming gone
