[PATCH] fbdev: Add helper to get an appropriate initial mode
Add new helper, fb_find_best_display(), which will search the modelist for the
best mode for the attached display. This requires an EDID block that is
converted to struct fb_monspecs and a private modelist. The search will be
done in this manner:
- if 1st detailed timing is preferred, use that
- else if dimensions of the display are known, use that to estimate xres and
- else if modelist has detailed timings, use the first detailed timing
- else, use the very first entry from the modelist
