Reset TSU6721 on initialization
Sometimes TSU6721 falls into a weird state where video dongle is
recognized as non-standard charger. Let's reset TSU6721 when EC boots,
so that we are guaranteed to have a clean state after initialization.
BUG=None
TEST=Keep doing Power+F3 reset. Doesn't see weird state anymore.
BRANCH=spring
