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

This patch adds 16-bit cmt platform data for the following cpus:
 - sh7619 (2 channels)
 - sh7203/sh7263 (2 channels)
 - sh7206 (2 channels)

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

 Periodic clockevent is tested on a rsk7203 board (sh7203).
 Clocksource support is currently disabled in the platform data.
