drm/msm/dp: support attaching bridges to the DP encoder
Currently DP driver will allocate panel bridge for eDP panels. This
supports only the following topology:
- eDP encoder ⇒ eDP panel (wrapped using panel-bridge)
Simplify this code to just check if there is any next bridge in the
chain (be it a panel bridge or regular bridge). Rename panel_bridge
field to next_bridge accordingly.
This allows one to use e.g. one of the following display topologies:
- eDP encoder ⇒ ptn3460 ⇒ fixed LVDS panel
- eDP encoder ⇒ ptn3460 ⇒ LVDS connector with EDID lines for panel autodetect
- eDP encoder ⇒ ptn3460 ⇒ THC63LVD1024 ⇒ DPI panel.
- eDP encoder ⇒ LT8912 ⇒ DSI panel
