eve: Wake AP on DP AltMode Entry & Attention.
This commit allows eve to wake from suspend when the device enters
DisplayPort Alternate mode and if an attention VDM is received while in
the mode. Note that since our policy is to be a sink only during
suspend, only powered charge through hubs with external display
capability will wake us up.
BUG=chromium:985228
BRANCH=firmware-eve-9584.B
TEST=Flash eve; suspend DUT, plug in powered charge through hub,
verify that DUT wakes up.
TEST=Use a powered MST hub, plug in a second monitor, verify DUT wakes
up as well.
