[Intel-gfx] [PATCH 3/3] Add the default modes for LVDS

[yakui_zhao]

In UMS mode the default modes will always be added for the LVDS output device 
regardless whether the EDID is returned.
Add the defaults mode for LVDS so that in KMS mode we can get the same modelines
as that in UMS mode . Otherwise the number of modelines in KMS will be less than
that in UMS mode.
