[ARM] 5311/1: ep93xx: add core support for built in i2c bus

Allow the ep93xx platform init code to register the built-in i2c bus.

The EP93xx processor has two GPIO pins dedicated for an I2C bus. This
patch registers the platform supplied i2c_board_info and the necessary
platform_device information for the i2c-gpio driver to use these pins.
