Support PCI-e device hot-add multi-function via device_add, just ensure

This patch doesn't seem to account of AIR though.
Yes, but the AIR function seems never be used(nobody calls the function
pcie_ari_init()), so I am a little confused about should it be consindered?
Yes please - we'll likely use that in the future. Pls add an API
that takes ari into account.
Ok, I am on it
changelog:
1. Flag device as unexposed when func 0 doesn`t exist, via return 0xFF
in case of gratuitous pci bus scan.
2. Since device is unexposed to guest, can remove function individually,
without interaction with the guest.

enable multi-function hot-add
remove function during multi-function hot-add
