[Skiboot] [PATCH] doc: add entry for OPAL_CHECK_ASYNC_COMPLETION

[Breno Leitao]

Currently there is no documentation for function #86, aka
OPAL_CHECK_ASYNC_COMPLETION, which is used on both Linux and FreeBSD,
but not documented yet.

This patch simply adds an initial entry for this function on
OPAL documentation.
