x86: Add a default implementation for cleanup_before_linux()

Browse Source 
This function provides an opportunity for some last minute cleanup and
reconfiguration before control is handed over to Linux. It's possible this
may need to do something in the future, but for now it's left empty. It's set
up as a weak symbol so it can be overridden if necessary on a case by case
basis.
