pcim_enable_device() no longer automatically manages IRQ vectors via

Drivers must now manually call pci_free_irq_vectors() for cleanup.
Alternatively,
pcim_alloc_irq_vectors() should be used.
This seems to break bisect. Surely you should update drivers before you
go changing behavior.
Patch 1 introduces pcim_alloc_irq_vectors() and then convert all needed
users to it. Then the final patch(37) remove the implict IRQ vector
management in pci_alloc_irq_vectors(). So the individual patch for each
driver should be safe IMO. And if these patches go via a single
tree with acks, it seems unlikely to break bisect.
