thunderbolt: Improve DisplayPort tunnel setup process to be more robust
[ Upstream commit b4734507ac55cc7ea1380e20e83f60fcd7031955 ]
After DisplayPort tunnel setup, we add verification that the DPRX
capabilities read process completed. Otherwise, we bail out, teardown
the tunnel, and try setup another DisplayPort tunnel using next
available DP IN adapter. We do so till all DP IN adapters tried. This
way, we avoid allocating DP IN adapter and (bandwidth for it) for
unusable tunnel.
