kernel/smp: Provide boot-time timeout for CSD lock diagnostics
Debugging of problems involving insanely long-running SMI handlers
proceeds better if the CSD-lock timeout can be adjusted. This commit
therefore provides a new smp.csd_lock_timeout kernel boot parameter
that specifies the timeout in milliseconds. The default remains at the
previously hard-coded value of five seconds.
