Public bug reported:
valgrind detects an uninitialised read on a value:
==29818== Conditional jump or move depends on uninitialised value(s)

This is because the stubbed version of AcpiOsReadPciConfiguration() does
nothing. Need to re-write AcpiOsReadPciConfiguration() to fake some
returned PCI config data.
