sh: trivial build cleanups.
Several errors were spotted during building for custom config (SMP included). Although SMP still does not compile (no ipi and __smp_call_function) and does not work, this looks a bit cleaner. Some other errors obtained via gcc-4.1.0 build. Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
