[1.] displayport MST external monitors don't return from sleep mode

[2.] When displays go to sleep, upon return from sleep the two monitors 
attached to a belkin mini displayport to 2x HDMI, do not return from 
sleep. This results in part of the desktop being inaccessible, until the 
external displays are unplugged, and then plugged back in.

Sometimes, Xorg will also back down to one monitor. The data 
accompanying this report is for an instance where the power save mode 
caused Xorg to drop to the primary monitor only.

This is on a Dell XPS 13 (9333) using intel i915. There are two external 
monitors connected by HDMI to a DP-MST adapter which connects to the 
single mini-displayport. A single-HDMI-to-mini-displayport adapter works 
as expected (coming out of power save).

The bug can be reproduced by either letting the screen power save 
timeout elapse, or by running "xset dpms force off"
