drm/mode: get the modeline for standard timing in EDID by using CVT/GTF
Create the standard timing modeline by using CVT/GFT algorithm while interpreting the EDID. In course of interpreting the EDID, the timing level will be obtained, which is used to determine whether the CVT/GTF algorithm is selected to generate the modeline for the given hdisplay/vdisplay/vrefresh_rate. In the UMS mode firstly it will check whether it can be found in the DMT table. If it can be found, then the modeline is returned. Then the timing_level is used to choose CVT/GTF. As there is no DMT table, no modeline is returned when timing level is DMT. For the other two timing levels, the CVT/GTF will be called to generate the required standard timing modeline.
