[PATCH] i2c: Let new-style drivers implement attach_adapter

[Jean Delvare <khali-PUYAD+kWke1g9hUCZPvPmw@public.gmane.org>]

While it isn't the way the standard device binding model works, it is
OK for new-style drivers to implement attach_adapter. It may help
convert the renaming legacy drivers to new style drivers faster.

Johannes, you'll need to apply this patch before you can test the
onyx/tas conversion patch I sent to you yesterday.
