coffeecake: Set Unconstrained Power (aka Ext) bit on 5V PDO
This bit needs to be set to allow Chromebooks to determine that the dock
is an externally powered DRP, so they'll try to charge from it instead of
sitting there with 5V 0A.
BRANCH=none
BUG=b:69056645
TEST=make buildall -j
Check that Chromebooks successfully charge from Coffee Cake.
