pd: use interrupt on Rx retry
After sending a message, we wait for up to 2.7 ms for reply. If we don't
get one, we retry for up to twice. Therefore, a undelivered message
could take up to >8ms. To prevent starving other tasks, let's yield to
other tasks on retries and rely on interrupt to wake us.
BUG=chrome-os-partner:28341
TEST=Plug in zinger on port 0 and C-to-A dongle on port 1. Check that
port 0 drops connection less frequently.
BRANCH=None
