Currently, on OMAP5, i2c1 and i2c5 defer probe due to pinctrl dependencies. This changes the i2c ID each bus is registered with in i2c-dev interface. As a result of this, many userspace tools break and there is no consistent manner to fix the same if the i2c dev interface have no consistent numbering. Since this could happen for other OMAP derivatives, provide i2c alias for all OMAP3+ SoCs to allow ordering the i2c devices correctly.
