This is a re-write of my previous response, as I should have reviewed it before submitting. I have simply been too excited! ;-)

I have upgraded to Ubuntu 17.10 and used the suggested nouveau.modeset=0 kernel boot option.
It works perfectly. I can indeed see many improvements. Most and foremost Wayland is working as far as I can see!
The only hiccup I had was with the laptop suspending right after a successful login, when the laptop lid was closed while being connected to the Dell Thunderbolt dock – TB16. In contrast to previous Ubuntu version there is no way of configuring the laptop lid closed behaviour by using the GUI (via Power configuration).
Below setting made the trick.
vim ~/etc/systemd/logind.conf
---
HandleLidSwitchDocked=ignore

In the light of this I believe this bug is addressed by upgrading to 17.10 and therefore this bug can be closed.
@Marco Scavazzon I believe you should create a new bug and reference this bug in order to get kernel 4.13.0-16 ported to Ubuntu 16.04 LTS.
@All Ubuntu kernel developer
A great thank you to you all for your efforts of making Ubuntu 17.04 so nicely work with Wayland and with Dell XPS 15 (9560)!!
