arm64: Allow CPUs unffected by ARM erratum 1418040 to come in late
[ Upstream commit ed888cb0d1ebce69f12794e89fbd5e2c86d40b8d ]
Now that we allow CPUs affected by erratum 1418040 to come in late,
this prevents their unaffected sibblings from coming in late (or
coming back after a suspend or hotplug-off, which amounts to the
same thing).
To allow this, we need to add ARM64_CPUCAP_OPTIONAL_FOR_LATE_CPU,
which amounts to set .type to ARM64_CPUCAP_WEAK_LOCAL_CPU_FEATURE.
Fixes: bf87bb0881d0 ("arm64: Allow booting of late CPUs affected by erratum 1418040")
