    drm/i915: clean up crtc timings computation

Description:
--------------------
This issue happens on HSW Harris Beach ULT, this machine has eDP and miniHDMI
display ports. I tested extension mode under gnome and found that HDMI can't
extend as left-of eDP. With two monitors plugged in and start X and gnome,
display is extension mode as default. The default extension mode is HDMI
right-of eDP(as picture I attached). Then I set HDMI left-of eDP, but can't
work(also looks like default mode). 

Here I attach system boot dmesg and Xorg.0.log.

Reproduce Steps:
--------------------
1. xinit&
2. gnome-session&
3. xrandr --output HDMI1 --left-of eDP1
