powerpc/64s: Fix POWER9 DD2.2 and above in DT CPU features
The CPU_FTR_POWER9_DD2_1 flag is intended to be set for DD2.1 and above (which is what the cputable setup does). Fix DT CPU features quirk setup to match. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> [mpe: Merge with upstream changes] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
