powerpc/476: define specific cpu table entry DD2 core
The DD2 core still has some unstability. Define CPU_FTR_476_DD2 to enable workarounds in later patches. This is based on an earlier, unreleased patch for DD1 by Ben Herrenschmidt. Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
