[BUG] xhci_hcd 0000:0f:00.0: controller declared dead on resume from suspend

Hardware:
  CPU: AMD Ryzen 9 7900 12-Core Processor
  Board: ASUS PRIME B650-PLUS
  Controller: AMD Raphael/Granite Ridge USB 2.0 xHCI [1022:15b8]
  Subsystem: ASUSTeK Computer Inc. [1043:8877]
  PCI: 0000:0f:00.0 (IOMMU group 30)

Software:
  Kernel: 7.0.0-rc5 (commit be762d8b, built 2026-03-28)
  Distro: Fedora 43 (Workstation)
  Desktop: GNOME on Wayland

Description:
  On the first suspend/resume cycle after boot, the xHCI controller at
  0000:0f:00.0 (AMD Raphael/Granite Ridge USB 2.0) fails to resume and
  is declared dead. A Logitech Unifying Receiver (046d:c52b) on this
  controller is disconnected and the mouse (Logitech M720 Triathlon)
  stops functioning.

  A second xHCI controller on the same system (0000:0c:00.0, AMD 600
  Series Chipset USB 3.2 [1022:43f7]) also errors on resume (USBSTS
  0x401) but successfully recovers via reinit. The 0f:00.0 controller
  does not recover.

  Regression from rc4: suspend/resume worked correctly on 7.0-rc4 and
  earlier kernels on the same hardware.

Reproduce:
  1. Boot with USB device attached to a port on the 0000:0f:00.0 controller
  2. Suspend (systemd suspend)
  3. Resume

dmesg on resume:
  xhci_hcd 0000:0f:00.0: xHCI host not responding to stop endpoint command
  xhci_hcd 0000:0f:00.0: xHCI host controller not responding, assume dead
  xhci_hcd 0000:0f:00.0: HC died; cleaning up
  xhci_hcd 0000:0c:00.0: xHC error in resume, USBSTS 0x401, Reinit
  usb usb1: root hub lost power or was reset
  usb usb2: root hub lost power or was reset
  usb 1-7: WARN: invalid context state for evaluate context command.
  usb 1-10: WARN: invalid context state for evaluate context command.
  usb 7-1: USB disconnect, device number 2

Workaround:
  PCI remove + rescan recovers the controller:
    echo 1 > /sys/bus/pci/devices/0000:0f:00.0/remove
    echo 1 > /sys/bus/pci/rescan

  A simple PCI device reset (echo 1 > .../reset) was insufficient -- the
  controller came back but did not re-enumerate the attached device.

Notes:
  - The 0f:00.0 controller is USB 2.0 only (USB3 root hub has no ports)
  - hci version 0x120, hcc params 0x0110ffc5, quirks 0x0000000200000010
