i2c: Migration aids for i2c_adapter.dev removal
Flag i2c_adapter.dev for removal after userspace tools get upgraded, and
include a near-term code migration aid to facilitate this:
- The class device gets the name attribute it should have had. This
was previously (wrongly) associated with the i2c_adapter.dev node.
Sysfs based tools and libraries can start converting right away.
- Issue a warning for legacy adapter drivers that don't provide any
physical device node; so systems with those drivers will know to
fix this problem earlier.
This is one of a series of patches to help the I2C stack become a better
citizen of the Linux Driver Model world.
