reef: enable tcpc-controlled drp toggle
BUG=chrome-os-partner:54668
BRANCH=none
TEST=Verified SNK is detected in S0 (toggle on), S3 (toggle off),
and S5 (force sink). SRC is detect in S0 only, stays detected when
entered S3, but unplug/plug while in S3 will not re-detect until
system back in S0. When go to S5, SRC will get disconnected until
back in S0, and hotplug SRC in S5 will not get detected. Checked
power role swap with another chromebook in the above scenario also.
