powerpc/mpc85xx: Add workaround for erratum A-005125
In a very rare condition, a system hang is possible when the e500 core
initiates a guarded load to PCI / PCIe /SRIO performs a coherent write
to memory. Please refer to errata document for more details. This erratum
applies to the following SoCs and their variants, if any.
