[PATCH v4 3/3] Documentation: Coccinelle: Modify Parallelisation information in docs

[Sumera Priyadarsini]

This patchset modifies coccicheck to use at most one thread per core by
default in machines with more than 4 hyperthreads for optimal performance.
Modify documentation in coccinelle.rst to reflect the same.
