Ethan Zhao e33ee8d5e6 PCI: Make pci_dev_is_disconnected() helper public for other drivers ...

[ Upstream commit 39714fd73c ]

Make pci_dev_is_disconnected() public so that it can be called from
Intel VT-d driver to quickly fix/workaround the surprise removal
unplug hang issue for those ATS capable devices on PCIe switch downstream
hotplug capable ports.

Beside pci_device_is_present() function, this one has no config space
space access, so is light enough to optimize the normal pure surprise
removal and safe removal flow.
