[PATCH 2/3] drm/msm: dsi host: Use device graph parsing to parse connected panel

The dsi host looks for the connected panel node by parsing for a child named 'panel'. This hierarchy isn't very flexible. The connected panel is forced to be a child to the dsi host, and hence, a mipi dsi device. This isn't suitable for dsi devices that don't use mipi dsi as their control bus.
