pd: change receive timeout to 1.8ms
Change PD receive timeout to 1.8ms. The max packet ever received
should be ~1.59ms, so this should be safe.
BUG=chrome-os-partner:33693
BRANCH=samus
TEST=load onto zinger and samus and connect a bunch of times.
also tested with PD communication disabled on samus and verified
that zinger sends source cap 50 times (each with 4 retries) and
then stops.
