[PATCH 05/05] sh: add IORESOURCE_CLK to SuperH Mobile I2C platform data

[Magnus Damm <magnus.damm@gmail.com>]

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

This patch passes processor specific IORESOURCE_CLK information to the
i2c-sh_mobile driver. With this change the clock to the IIC block will
be disabled while the I2C bus is inactive. Without this patch the clock
is always on.
