Removed xhci_hcd.quirks=0x80 from kernel command line as suggested.

Suspend/resume now works correctly:

  PM: suspend entry (s2idle)
  xhci_hcd 0000:00:0d.0: xhci_suspend: stopping usb1 port polling.
  xhci_hcd 0000:00:14.0: xhci_suspend: stopping usb3 port polling.
  xhci_hcd 0000:00:0d.0: xhci_resume: starting usb1 port polling.
  xhci_hcd 0000:00:14.0: xhci_resume: starting usb3 port polling.
  r8152-cfgselector 2-3.1: usb resume
  r8152-cfgselector 2-3.1: finish resume
  r8152 2-3.1:1.0 enp0s13f0u3u1: carrier on
  PM: suspend exit

No "root hub lost power" messages. Ethernet recovers at SuperSpeed.
Full dmesg with xhci_hcd and usbcore debug attached.

Thanks for identifying the root cause.
