The EDID lists two modes (one for 60 Hz refresh rate and one for 40 Hz), so we'll list both of them here. Note that the panel datasheet requires 80 ms between HPD asserting and the backlight power being turned on. We'll use the new timing constraints structure to do this cleanly. This assumes that the backlight will be enabled _after_ the panel enable finishes. This is how it works today and seems a sane assumption.
