Bug description:
  [SRU Justifcation]

  [Impact]

  Devices affected:

  * [1022:148c] USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] 
Starship
    USB 3.0 Host Controller
  * [1022:149c] USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] 
Matisse
    USB 3.0 Host Controller
  * [1022:1487] Audio device [0403]: Advanced Micro Devices, Inc. [AMD]
    Starship/Matisse HD Audio Controller

  Despite advertising FLReset device capabilities, performing a function level
  reset of either of these devices causes the system to lock up. This is of
  particular issue where these devices appear in their own IOMMU groups and are
  well suited to VFIO passthrough.

  Issue was introduced in AMD's "AGESA Combo-AM4 1.0.0.4 Patch B" microcode
  update, and affects dozens of motherboard models across various vendors.

  Additional discussion of this issue:
  
https://www.reddit.com/r/VFIO/comments/eba5mh/workaround_patch_for_passing_through_usb_and/

  [Fix]

  Two commits currently landed in linux-pci pci/virutualization:
  * 0d14f06cd665 PCI: Avoid FLR for AMD Matisse HD Audio & USB 3.0
  * 5727043c73fd PCI: Avoid FLR for AMD Starship USB 3.0

  [Test Case]

  Peform the test on an impacted system:

  * B350, B450, X370, X470, X570 motherboards (practically anything with an AM4
    socket);
  * Ryzen 3000-series CPU (2000-series possibly also affected);
  * BIOS/UEFI firmware that includes "AGESA Combo-AM4 1.0.0.4 Patch B" (check
    vendor release notes)

  In the above case where '0000:10:00.3' is the USB controller '1022:149c', 
issue
  a reset command:

    $ echo 1 | sudo tee /sys/bus/pci/devices/0000\:10\:00.3/reset

  Impacted systems will not return successfully and become unstable, requiring a
  reboot. `/var/logs/syslog` will show something resembling the following:

    xhci_hcd 0000:10:00.3: not ready 1023ms after FLR; waiting
    xhci_hcd 0000:10:00.3: not ready 2047ms after FLR; waiting

    TSC found unstable after boot, most likely due to broken BIOS. Use

-2209419)

  [Regression Risk]
  Low. These two patches affect only systems with a device needs fix.
