powerpc/mpc85xx: work around erratum A-006593
Erratum A-006593 is "Atomic store may report failure but still allow the store data to be visible". The workaround is: "Set CoreNet Platform Cache register CPCHDBCR0 bit 21 to 1'b1. This may have a small impact on synthetic write bandwidth benchmarks but should have a negligible impact on real code."
