Actually, it's not as inconsistent as you claim.

c68b0274fb3c ("ARM: reduce "Booted secondary processor" message to debug level")
dropped the corresponding pr_info() in the bringup path to debug level,
so to be consistent, this one should be dropped to debug level too.

Removing it arguably makes it more inconsistent!

So, I'd be willing to accept a patch lowering this to a pr_debug()
to make it more consistent with the bringup path, but otherwise the
consistency argument doesn't really stand.
