arm: socfpga: Add I2C support to SoCFPGA

This patch adds I2C support for the SoCFPGA. Using the designware I2C
controller driver. It supports all 4 I2C busses on the SoCFPGA.

The designware I2C driver has now been converted to the
CONFIG_SYS_I2C framework. So lets enable it on SoCFPGA.

Tested on SoCrates.
