[PATCH V3 1/2] PCI: Try to clean up resources via remove if shutdown doesn't exist

It is up to a driver to implement shutdown() callback. If shutdown() callback is not implemented, PCI device can have pending interrupt and even do DMA transactions while the system is going down. If kexec is in use, this can damage the newly booting kexec kernel or even prevent it from booting
