pd: add option to save power in S5

Browse Source 
When we are in sink mode and not dual-role toggling, add the option to
disable the CC lines polling every 10 ms (thus waking up on the VBUS
transition or the 1-minute slow polling).

BRANCH=smaug
BUG=chrome-os-partner:44229
TEST=on Smaug DVT, measure power consumption in S5 and wake-up time when
