USB MUX: Update low power mode of MUX anx7447 used as MUX only
In order to improve power consumption of daughter board in Beadrix project,
we figure out the key components include MUX. We add a low power mode
function of anx7447 used as MUX only. The measured power consumption of
daughter board is reduced from 90~108 mW to 5~10 mW.
BRANCH=main
BUG=b:216050967
TEST=on beadrix, measure power consumption of daughterboard with PD C1
MUX ANX3447QN-AC-R. The measured power consumption of daughterboard is
improved.
