xhci: move PCI specific MSI/MSIX cleanup away from generic xhci functions

Browse source 
Call the PCI specific MSI/MSIX interrupt freeing code from the xhci-pci
callbacks instead of generic xhci code, decoupling PCI parts from
generic xhci functions.

Adds xhci_pci_stop() that overrides xhci_stop() for PCI xHC controllers.

This will free MSIX interrupts a bit later in the hc_driver stop
callback, but is still earlier than usb core frees "legacy" interrupts,
or interrupts for other hosts.
