[RFC PATCH 1/2] bust_spinlocks: add kernel-doc format doc

In the ELISA Linux Foundation project we are trying to
improve the functions' documentation to make it more suitable
to derive functions' specs and write unit tests. This is needed
to make Linux more usable in functional safety systems.
So I am adding a proper kernel-doc format for bust_spinlocks.

With respect to this patch I have a question on how to set
the function context; i.e. I don't know if it can be executed
in any context or if it has limitations.
