[PATCH 10/13] drm/amd/display: create a function to fill dc_sink with edid data

[Melissa Wen]

From: Rodrigo Siqueira <siqueira at igalia.com>

As part of the effort of stopping using raw edid, this commit move the
copy of the edid in DC to a dedicated function that will allow the usage
of drm_edid in the next steps.
