drm_edid: There should be 6 Standard Timings
Smatch complained that we initialize 6 elements in add_detailed_modes() but the timings[] array is declared with 5 elements. Adam Jackson verified that 6 is the correct number of timings.

I don't have the docs for 1.2 or earlier, but we're > paranoid enough about not adding broken timings that we should be fine. This patch is basically a clean up, because timings[] is declared inside a union and increasing the number of elements here doesn't change the overall size of the union.
