drm/display: Make DisplayPort tunnel debug Kconfig name consistent

While most display helpers Kconfig symbols have the DRM_DISPLAY prefix,
the DisplayPort Tunnel debugging uses DRM_DISPLAY_DEBUG_DP_TUNNEL_STATE.

Since the number of users is limited and it's a selected symbol, we can
easily rename it to make it consistent.
