Boot BDW with HDMI connected. But after suspend and resume, HDMI screen does not show the xterm with "xrandr --output eDP1 --rotation left --output HDMI1 --rotation right".

1. Connect HDMI display to BDW and boot BDW
2. xinit #This will show xterm on both eDP and HDMI screen
3. xrandr --output eDP1 --rotation left --output HDMI1 --rotation left
4. echo mem > /sys/power/state
5. xrandr --output eDP1 --rotation left --output HDMI1 --rotation right
xterm shows on eDP but disappears on HDMI screen.

Test it on the latest drm-intel-nightly_fb4572_20150806+ kernel, this bug has gone away.
Verified it.
