Subject: [PATCH] sh: remove stray markers

arch/sh has a couple of stray markers without any users introduced
in commit 3d58695edbfac785161bf282dc11fd42a483d6c9.  Remove them in
preparation of removing the markers in favour of the TRACE_EVENT
macro (and also because we don't keep dead code around).

Paul, are you okay putting this in via the tracing tree?  I'd like
to have all marker removals queued up there so we can kill it in one
go once 2.6.31 opens.
