ARM: davinci: da850: add DT node for I2C0

Add I2C0 device tree and pin muxing information to da850-evm.
Also, add OF_DEV_AUXDATA for I2C0 controller driver in da850
board dt file to use I2C0 clock.
Verified i2c0 node gets created in sys class interface as
"/sys/class/i2c-dev/i2c-0/subsystem/i2c-0".

nsekhar@ti.com: tested using i2cdetect and i2cdump.
