[PATCH 1/2] edac: Use ccsr_pci structure instead of hardcoded define

[Chunhe Lan]

There are some differences of register offset and definition between
pci and pcie error management registers. While, some other pci/pcie
error management registers are nearly the same.

To merge pci and pcie edac code into one, it is easier to use ccsr_pci
structure than the hardcoded define. So remove the hardcoded define and
add pci/pcie error management register in ccsr_pci structure.
