PCI: Introduce pci_alloc_dev(struct pci_bus*) to replace alloc_pci_dev()
Here we introduce a new interface to replace alloc_pci_dev():
struct pci_dev *pci_alloc_dev(struct pci_bus *bus)
It takes a "struct pci_bus *" argument, so we can alloc a PCI device
on a target PCI bus, and it acquires a reference on the pci_bus.
We use pci_alloc_dev(NULL) to simplify the old alloc_pci_dev(),
and keep it for a while but mark it as __deprecated.
Holding a reference to the pci_bus ensures that referencing
pci_dev->bus is valid as long as the pci_dev is valid.
[bhelgaas: keep existing "return error early" structure in pci_alloc_dev()]
