[PATCH 4/4] drm/bridge: ti-sn65dsi86: use helper to lookup panel-id

[Rob Clark <robdclark@gmail.com>]

From: Rob Clark <robdclark@chromium.org>

Use the drm_of_find_panel_id() helper to decide which endpoint to use
when looking up panel.  This way we can support devices that have
multiple possible panels, such as the aarch64 laptops.
