[PATCH 1/4] i2c: i2c-ocores - DT bindings and minor fixes.

["Jayachandran C" <jayachandranc-oSioyQM9ZPnuBjGU1YDckgC/G2K4zDHf@public.gmane.org>]

Cleanups to i2c-cores, no change in logic, changes are:
* Move i2c-ocores device tree documentation from source file to
  Documentation/devicetree/bindings/i2c/i2c-ocores.txt.
* Add \n to dev_warn and dev_err messages where missing
* Minor updates to the text and formatting fixes.
