thunderbolt: Changes for v7.3 merge window

This includes following USB4/Thunderbolt changes for the v7.3 merge
window:

  - Assert Downstream Port Reset for Thunderbolt 3 devices during
    shutdown to avoid unnecessary delays over warm reset.
  - Tidy up Thunderbolt service ->probe callbacks.
  - USB4STREAM improvements.
  - AMD host interface quirk to fix Tx ring hang on teardown of a DMA tunnel.
  - Minor fixes and cleanups.

All these have been in linux-next with no reported issues.
----------------------------------------------------------------
There is one merge conflict due to a changes to drivers/thunderbolt/nhi.c
done in the current release cycle. This is how I solved it:

diff --cc drivers/thunderbolt/nhi.c
index 35e3c119d5ee,914d4f8700b5..5809809f64d4
--- a/drivers/thunderbolt/nhi.c

@@@ -1235,6 -1274,10 +1276,8 @@@ int nhi_probe(struct tb_nhi *nhi
  
  	dev_dbg(dev, "NHI initialized, starting thunderbolt\n");
  
 -	init_completion(&nhi->domain_released);
 -
+ 	nhi->host_reset = host_reset;
+ 
  	res = tb_domain_add(tb, host_reset);
  	if (res) {
  		/*

Thanks!
