Subject: [PATCH] ARC: Remove ISS_SMP_EXTN entirely

The Kconfig symbol ARC_HAS_COH_RTSC was removed in v3.13. The Kconfig
entry for ISS_SMP_EXTN still had a select for that symbol. That select
was just removed in commit d345ea2892ae ("ARC: Remove
ARC_HAS_COH_RTSC").

But selecting ARC_HAS_COH_RTSC was the only thing ISS_SMP_EXTN ever
did. That means that since v3.13 setting ISS_SMP_EXTN was effectively a
nop anyhow. So ISS_SMP_EXTN can as well be removed entirely.
