[PATCH 02/18] ARM: ux500: Remove unused i2c platform_data initialisation code

[lee.jones@linaro.org (Lee Jones)]

Now that u5500 is obsolete, u8500 is the only user of the Nomadik
i2c driver. As such there is no requirement to differentiate between
initialisation values. By the time a new SoC is released, almost all
of the ux500 platform will be DT:ed, so we can make decisions based
on the compatible property instead.
