Subject: edac: Add edac_pci_alloc_index()
From: Harry Ciao <qingtao.cao@xxxxxxxxxxxxx>
Add edac_pci_alloc_index(), because for MAPLE platform there may exist
several EDAC driver modules that could make use of edac_pci_ctl_info
structure at the same time. The index allocation for these structures
should be taken care of by EDAC core.
