i2c: Kill i2c_adapter.class_dev

Kill i2c_adapter.class_dev. Instead, set the class of i2c_adapter.dev
to i2c_adapter_class, so that a symlink will be created for every
i2c_adapter in /sys/class/i2c-adapter.

The same change must be mirrored to i2c-isa as it duplicates some
of the i2c-core functionalities.

User-space tools and libraries might need some adjustments. In
particular, libsensors from lm_sensors 2.10.3 or later is required for
proper discovery of i2c adapter names after this change.

-What:   i2c_adapter.dev
-        i2c_adapter.list
+What:   i2c_adapter.list
 When:   July 2007
-Why:    Superfluous, given i2c_adapter.class_dev:
-          * The "dev" was a stand-in for the physical device node that legacy
-            drivers would not have; but now it's almost always present.  Any
-            remaining legacy drivers must upgrade (they now trigger warnings).
-          * The "list" duplicates class device children.
-        The delay in removing this is so upgraded lm_sensors and libsensors
-        can get deployed.  (Removal causes minor changes in the sysfs layout,
-        notably the location of the adapter type name and parenting the i2c
-        client hardware directly from their controller.)
+Why:    Superfluous, this list duplicates the one maintained by the driver
+        core.
