The pixel clock is conceptually part of the detailed timings, while it's
just zero padding for display descriptors. Modify the structures to
reflect this. Rename struct detailed_non_pixel to
edid_display_descriptor to better reflect spec while at it. (Further
struct renames are left for follow-up work.)
