sh: Simplify kernel_thread_helper() for sh32.
This can use the same implementation as sh64, the generated assembly is the same between the new and old version, so there is not much point in leaving it open coded in inline assembly. This is preparatory work for future consolidation of the _32/_64 variants. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
