Booting 3.8-rc6 on omap 5430evm results in the following error

omap_i2c 48070000.i2c: did not get pins for i2c error: -19
[    1.024261] omap_i2c 48070000.i2c: bus 0 rev0.12 at 100 kHz

[    1.064025] omap_i2c 4807a000.i2c: bus 3 rev0.12 at 400 kHz

This happens because omap5 dts file is not adapted to use i2c through pinctrl
framework. Populating i2c pinctrl data to get rid of the error.

Tested on omap5430 evm with 3.8-rc6 kernel.
