edac: add DDR3 memory type for MPC85xx EDAC
Since some new MPC85xx SOCs support DDR3 memory now, so add DDR3 memory type for MPC85xx EDAC. Signed-off-by: Yang Shi <yang.shi@windriver.com> Cc: Doug Thompson <norsk5@yahoo.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
