Sometimes HDMI1 would stop working after suspend/resume.
* By switching the cable to HDMI2 we can see that HDMI2 still works.
* A reboot is required to make HDMI1 work again.
* This issue cannot be reproduce if the monitor is connected to HDMI2 in the
first place.

This issue can be reproduced with 4.17-rc1, and also drm-tip/2018-04-19
(1c7ccdf37b04bedb10e2191d34dfbba62beb79ea).
