powerpc/eeh: pseries platform EEH operations
There're 4 EEH operations that are covered by the dedicated RTAS call <ibm,set-eeh-option>: enable or disable EEH, enable MMIO and enable DMA. At early stage of system boot, the EEH would be tried to enable on PCI device related device node. MMIO and DMA for particular PE should be enabled when doing recovery on EEH errors so that the PE could function properly again. The patch implements it and abstract that through struct eeh_ops::set_eeh. It would be help for EEH to support multiple platforms in future.
