Backport of SOF audio hang fix for X1 Carbon 9

This is a backport of https://github.com/thesofproject/linux/pull/2768

This is needed to fix a rare problem where the SOF audio driver hangs during a reboot. It occurs about once in 30 reboots and is hard to reproduce but has been seen on the X1 Carbon Gen9.

The backport wasn't clean. I backported the following commits from the https://github.com/thesofproject/linux repository 578778fd0c847b966679802dcb357b9d3acb44c8 8f31938cd1990138941d519cc571506070e4d9a0 a40cbfd2b54ea6d4698d2351b46fa0e958bf6220 0b3afc4b486b573c2e60eaf5684435a5d0b91828 31627609bbf60163317832644a241f6dc1f3e9b6 59737eaebfcc10cbb9f20166977185007bfd6da9

The last commit was extra and needed to add shutdown functionality. I implemented the change in penultimate commit in sof-pci-dev.c instead of pci-tgl.c as that file doesn't exist yet in this version of kernel. I wasn't sure if it was better to do a small surgical change, or to add in more commits - let me know if I need to tackle this differently

First time doing a backport to the Fedora kernel - let me know if there are any procedure or implementation preferences or errors
