Yes, this does the trick.
On 4.15 based kernel I can see the SoC enters PC10 but SLP_S0 is not
asserted.
On mainline kernel the SoC, PC10 is hit and SLP_S0 is asserted. Once SLP_S0
is asserted the SSH connection becomes really sluggish.

Is it possible to add Dynamic LTR as an option so users and downstream
distros can still benefit from it?
As I said before, this is not a stable solution. No guarantee that HW
will work as properly.
Can you describe the symptom of "HW will work as properly”? Is this the
sluggish connection I observed?
