[ Upstream commit f44bff19268517ee98e80e944cad0f04f1db72e3 ]
On powerpc, it is possible to compile test both the new apple (arm) and old pasemi (powerpc) drivers for the i2c hardware at the same time, which leads to a warning about linking the same object file twice:
scripts/Makefile.build:244: drivers/i2c/busses/Makefile: i2c-pasemi-core.o is added to multiple modules: i2c-apple i2c-pasemi
Rework the driver to have an explicit helper module, letting Kbuild take care of whether this should be built-in or a loadable driver.
