Currently, the existing PHBs are retrieved from the FDT (Flat Device Tree) based on the name of FDT node. Specificly, those FDT nodes whose names have prefix "pci" are regarded as PHBs. That's inappropriate because some PCI bridges possibilly have names leading with "pci". It caused EEH is enabled on same PCI devices for towice. The patch fixes the above issue. Besides, the PHBs are expected to be figured out from FDT before enable EEH on them. Therefore, it's resonable to retrieve the PHBs from the global linked list traced by variable "hose_list" insteading poking them from FDT. For the EEH implementation on pSeries platform, RTAS is critical because all low-level functions are implemented based on RTAS. Therefore, we should make sure "/rtas" OF node is available and ready before to enable EEH core. However, it actually introduced duplicate since the previous pSeries platform dependent initialization function already do the check. Besides, we want to make eeh core platform independent, so RTAS related staff should be removed there. The patch removes the duplicate check on "/rtas" OF node for eeh core.
