lspci: Build tree based on PCI_FILL_PARENT information

Topology reported by system (libpci provider) may be different from
topology built based on primary/secondary/subordinate numbers from PCI
bridges by lspci.

This happens for example when some non-compliant PCI-to-PCI bridge
with Type 0 header (e.g. Marvell one) is available in the system.

So add additional edges reported by libpci when building tree in lspci.
