[PATCH] sh: TMU platform data for sh7785

[PATCH] sh: TMU platform data for sh7785

[Magnus Damm]

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

This patch adds TMU platform data for sh7785. Both clockevent
and clocksource support is enabled.

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

 Tested on sh7785lcr and r7785 highlander.

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