During early days of PCI quirks support ThunderX firmware did not provide
PNP0c02 node with PCI configuration space and PEM-specific register ranges.
This means that for legacy FW we are not reserving these resources and
cannot gather PEM-specific resources for further PEM initialization.

In order to support already deployed legacy FW calculate PEM-specific ranges
and provide resources reservation as fallback scenario into PEM driver when
we could not gather PEM reg base from ACPI tables.
