ppc/pnv: Add POWER10 ChipTOD quirk for big-core
POWER10 has a quirk in its ChipTOD addressing that requires the even small-core to be selected even when programming the odd small-core. This allows skiboot chiptod init to run in big-core mode. Reviewed-by: Cédric Le Goater <clg@redhat.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
