MIPS: Octeon: Apply CN63XXP1 errata workarounds.
The CN63XXP1 needs a couple of workarounds to ensure memory is not written
in unexpected ways.
All PREF with hints in the range 0-4,6-24 are replaced with PREF 28. We
pass a flag to the assembler to cover compiler generated code, and patch
uasm for the dynamically generated code.
The write buffer threshold is reduced to 4.
