Christian Helmuth df1767b784 vbox6: tidy up devxhci poweroff 
The issue came apparent with Windows Guests and USB passthrough of
smart-card readers. If the VM is powered off, PDMR3Term cleans up all
devices incl. (first) acpi and (later) devxhci. The latter used a
dangling reference to ACPI structs in a indirect call to
apicIsLogicalDest() from xhciR3Destruct().

  VMMR3_INT_DECL(int) PDMR3Term(PVM pVM)
      virtualbox6/src/VBox/VMM/VMMR3/PDM.cpp:817

      "apic" (pDevIns->pReg->szName)

          static void apicR3TermState(PVM pVM)
              virtualbox6/src/VBox/VMM/VMMR3/APIC.cpp:1235

      "qemu-xhci" (pDevIns->pReg->szName)

          static DECLCALLBACK(int) xhciR3Destruct(PPDMDEVINS pDevIns)
              repos/ports/src/virtualbox6/devxhci.cc:431

          void usb_detach(USBPort *port)
              <qemu-usb>/src/lib/qemu/hw/usb/core.c:70

          static void xhci_port_notify(XHCIPort *port, uint32_t bits)
              <qemu-usb>/src/lib/qemu/hw/usb/hcd-xhci.c:2592

          static DECLCALLBACK(void) pciSetIrq(PPDMDEVINS pDevIns, PPDMPCIDEV pPciDev, int iIrq, int iLevel, uint32_t uTagSrc)
              virtualbox6/src/VBox/Devices/Bus/DevPCI.cpp:398

          static bool apicIsLogicalDest(PVMCPUCC pVCpu, uint32_t fDest)
              virtualbox6/src/VBox/VMM/VMMAll/APICAll.cpp:797

The fix removes our Qemu library reset from xhciR3Destruct() and
registers xhciR3Reset() as PowerOff hook.

Thanks to Raphael for the thorough investigation.

README 

This directory contains ports of popular 3rd-party applications to Genode.

The 'ports' repository follows the line of the 'libports' repository.
For instructions about downloading and building 3rd-party applications,
please refer to 'libports/README'.


Dependencies from other repositories

Application provided by the 'ports' repository typically expect a rich
runtime environment, including shared libraries provided by the 'libports'
repository. Hence, 'ports' depends on 'libports'.
