[media] vivid: fix g_edid implementation
The VIDIOC_G_EDID implementation in vivid didn't take edid->start_block into account when copying the EDID data. Make sure that the internal EDID is updated with the correct CEC physical address. Currently the returned EDID is updated, but that will only work well if edid->start_block is 0.
