soc/intel/tigerlake: Invoke PCIe root port swapping
PCIe bus:function specifiers need to be coalesced the same way
functions are coalesced during bus enumeration. Invoke PCIe root port
devicetree update to swap the enabled root port devices with the
disabled devices.
At this point, the TGL pci_devs.h only describes the PCH-LP, so only
the PCH-LP root ports are listed in this patch. We'll need to add
additional PCIe root ports when PCH-H support is added.
BUG=b:162106164
TEST=Ensure that the PCIe device 1c.7 corresponding to Root port 8 is
swapped with the PCIe device 1c.0 corresponding to Root port 1.
