common: pd_policy: Add notification for DP AltMode
This commit simply adds a notification that can be called when the
device enters DisplayPort Alternate mode or a DP attention VDM is
received. Calling the notification will send a MODE_CHANGE host event
which may wake the AP.
BUG=chromium:786721
BRANCH=firmware-nocturne-10984.B
TEST=With other patches, flash nocturne; suspend DUT, plug in powered
charge through hub, verify DUT wakes up.
