Clang 3.4 considers duplicate typedef in ppc4xx_i2c.h and
bitbang_i2c.h an error even if they are identical. Move it to a common
place to allow building with this clang version.

Peter, in case you've got to roll another rc, I think this should be
included, too. Otherwise, I think this can also be included later via
qemu-stable (for the few people like me who still use clang 3.4).

Would this also be an opportunity to rename the struct to something 
CamelCase to match our coding conventions?

That's a different issue, so I'd say it should be done in a different patch.
