With TPL we don't need full PCI support and it adds to code size. Instead, a simple_bus driver is good enough to be able to read and write the PCI config and do a little basic setup.
So at present there are two drivers in U-Boot called pci_x86. One is in UCLASS_PCI, used in SPL and U-Boot proper. The other is in UCLASS_SIMPLE_BUS and used only in TPL.
Add a tag to tell dtoc about this, so it knows which one to use when generating the devices and uclasses.
