i2c: sh_mobile: remove platform_data
No platform currently upstream makes use of this platform_data anymore. The ones that did are converted to DT meanwhile. So, remove it. The old platforms likely don't have the 'clks_per_cnt' feature, otherwise it would have been implemented by now. And in the unlikely case they need to setup a different bus speed, we should rather go for a generic i2c platform data just for that.
