[PATCH] sh: TMU platform data for sh7723

[PATCH] sh: TMU platform data for sh7723

[Magnus Damm]

From: Magnus Damm <damm@igel.co.jp>

This patch adds TMU platform data for sh7723. Both clockevent
and clocksource support is enabled. While at it, adjust the
CMT clocksource rating to prioritize the TMU.

Signed-off-by: Magnus Damm <damm@igel.co.jp>

 Tested on ap325.

 For correct run-time behaviour this patch is needed:
 "clocksource: setup mult_orig in clocksource_enable()"
