pcidev: Construct a API to handle phantom pci controllers
On Intel the SPI PCI device can have hiden PCI vendor
and device IDs. So we need a PCI access method that works
even when the OS doesn't know the PCI device.
This however does not generalise since it would bring along other
constraints (e.g. on PCI domains, extended PCIe config space).
Fortunately the logic exists inside chipset_enable.c however
the interaction with the rest of the pcidev workers are quite
invasive and hard to reason about. Therefore here we implement
a definable API to manage this special casing by having methods
define on a handle with a known life-time.

TEST=`sudo ./flashrom -p internal -r /tmp/bios`
on Found chipset "Intel Kaby Lake U w/ iHDCP2.2 Prem.".
