Subject[PATCH -next] PM: tools: add "CPU killed" timeline on arm64 platform
Date
On the arm64 platform, the core log of cpu offline is as follows:

[ 100.431501] CPU1: shutdown
[ 100.454820] psci: CPU1 killed (polled 20 ms)
[ 100.459266] CPU2: shutdown
[ 100.482575] psci: CPU2 killed (polled 20 ms)
[ 100.486057] CPU3: shutdown
[ 100.513974] psci: CPU3 killed (polled 28 ms)
[ 100.518068] CPU4: shutdown
[ 100.541481] psci: CPU4 killed (polled 24 ms)

'smpboot: CPU (?P<cpu>[0-9]*) is now offline' cannot be applied
to the arm64 platform, which caused the loss of the suspend
machine stage in S3. Here I added core code to fix this issue.
