Sachin Kamat cd5006db1b i2c: s3c2410: Trivial cleanup in header file
Commit 436d42c61c ("ARM: samsung: move platform_data definitions")
moved the files to the current location but forgot to remove the pointer
to its previous location. Clean it up. While at it also change the header
file protection macros appropriately.
