[PATCH v2 9/9] x86: Add cleanup_before_linux()

[Simon Glass]

This function is not present on x86, but there is an x86-specific
version which is never called. This is a bug, meaning that APs are not
parked before booting.

The original weak function was added in 2012 by:
commit f30fc4de4160 ("x86: Add a default implementation for 
cleanup_before_linux()")

At later change made use of the weak function but was actually dead
code. The Fixes tag reflects that.

Add cleanup_before_linux(), making it call x86_cleanup_before_linux()

Fixes: 99a573fb326f ("x86: mp: Park CPUs before running the OS")
