sh: Wire up oops reporting in the die notifier chain.
Commit 3f5a54e371ca20b119b73704f6c01b71295c1714 ("ftrace: dump out ftrace buffers to console on panic") added an ftrace buffer dumper that hooks in to the die notifier chain and dumps out data in the oops path. Unfortunately SH supported ftrace but didn't support DIE_OOPS, so add that in and get it building again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
