arm64: remove dead-code depending on CONFIG_UP_LATE_INIT
Commit 4b3dc9679cf7 ("arm64: force CONFIG_SMP=y and remove redundant and therfore can not be selected anymore. Remove dead #ifdef-block depending on UP_LATE_INIT in arch/arm64/kernel/setup.c Signed-off-by: Jonas Rabenstein <jonas.rabenstein@studium.uni-erlangen.de> [will: kill do_post_cpus_up_work altogether] Signed-off-by: Will Deacon <will.deacon@arm.com>
