Subject: [PATCH] powerpc/powernv: Ignore smt-enabled on Power8 and later

Starting with POWER8, the subcore logic relies on all threads of a core
being booted so that they can participate in split mode switches. So on
those machines we ignore the smt_enabled_at_boot setting (smt-enabled on
the kernel command line).
