[PATCH v13 1/2] arm/pci: add pci_passhtrough_enabled check to pci_device_reset

Without pci-passthrough=on Xen does not know anything about present PCI devices due to PHYSDEVOP_pci_device_add not executing. This causes PHYSDEVOP_pci_device_reset to fail when trying to find the device that is being reset and return ENODEV. Add explicit is_pci_passthrough_enabled check to retur
