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.

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.
