p9.pci.scan.initfile -- replace 62028 implementation with initfile entry

62028 added a workaround for SW 430383, using a manual re-scan of the ring
hardcoded to flip the desired bits because engineering data was not yet
available for the necessary spies

This commit removes the SBE manual scan sequence and sets the necessary
chicken switches by the newly added spy entries
