kernel-doc complains about missing "Return" section for the function
regulator_irq_map_event_simple().

Add a "Return" section for it based on its behavior. The function
actually always returns 0, but fills in fields in its @rid parameter as
needed. Expand the description of the parameter to cover this.

While at it fix a typo found in the description of the same function.

Closes: https://lore.kernel.org/all/e341240e-1c1f-49a2-91cd-440888fdbda0@gmail.com/

- Add period ('.') to the end of the "Return" section sentence
