Configure BAR and MSI for Thor. Add checks for chip id for chip specific code between Orin and Thor. Separate Stream ID's are assigned to upstream and downstream struct device in Rootport client driver. While accessing Rootport local memory upstream Stream ID should be used. While accessing memories over BAR downstream Stream ID should be used.
