sh: TMU platform data for sh7722
This patch adds TMU platform data for sh7722. Only clockevent mode is enabled for now, clocksource requires this patch: "clocksource: setup mult_orig in clocksource_enable()" Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
