Correction: This series will support only i2c1 controller and it will not
handle i2c1 child devices such as twlxxxx pmic. Due to which, twl read/write's
might fail during boot.

I am facing issues in getting platform_data in i2c child device probe function.
The issue is reported to grant in patch 08/13 of this series.
