video: display: refactor display_read_timing to avoid code duplication

Browse Source 
Commit 2dcf143398ad ("dm: video: Repurpose the 'displayport' uclass to 'display'")
left the display_read_edid() function unused by mistake.

Mark the function as static and reuse it within display_read_timing() to
avoid code duplication.
