x86: tpl: Add a fake PCI bus

We can use fixed BARs and drivers can directly program the devices that
they need.

However we do need to bind the devices on the PCI bus and without PCI this
does not ordinarily happen. As a work-around, define a fake PCI bus which
does this binding, but no other PCI operations. This is a convenient way
to ensure that we can use the same device tree for TPL, SPL and U-Boot
proper:

   TPL    - CONFIG_TPL_PCI is not set (no auto-config, fake PCI bus)
   SPL    - CONFIG_SPL_PCI is set (no auto-config but with real PCI bus)
   U-Boot - CONFIG_PCI is set (full auto-config after relocation)
