i2c-ibm_iic: Remove deprecated OCP style part
The deprecated OCP style driver part is used by the "old" arch/ppc platform. This platform is scheduled for removal in June/July this year. This patch now removes the OCP driver part from the IBM I2C driver. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>
