[PATCH] [POWERPC] i2c: fix build breakage introduced by OF helpers

[Jochen Friedrich <jochen@scram.de>]

Fix build breakage introduced in commit
"[POWERPC] i2c: OF helpers for the i2c API".
If i2c-core is compiled as module, the helper needs to be
compiled as module, as well. Rename i2c.c to of_i2c.c to
avoid name space conflict.
