YAMAMOTO Takashi 4c3ae2ed4f Revert "sem: change sem wait to atomic operation" ...

This reverts commit befe29801f.

Because a few regressions have been reported and
it likely will take some time to fix them:

* for some configurations, semaphore can be used on the special
  memory region, where atomic access is not available.
  cf. https://github.com/apache/nuttx/pull/14625

* include/nuttx/lib/stdatomic.h is not compatible with
  the C11 semantics, which the change in question relies on.
  cf. https://github.com/apache/nuttx/pull/14755
