[efi] Allow EFI to control PCI bus enumeration
EFI performs its own PCI bus enumeration. Respect this, and start
controlling devices only when instructed to do so by EFI.
As a side benefit, we should now correctly create multiple SNP
instances for multi-port devices.
This should also fix the problem of failing to enumerate devices
because the PCI bridges have not yet been enabled at the time the iPXE
driver is loaded.
