As Kay Sievers explained that i2c adapters should be bus devices rather
than class devices, convert them.
[PATCH 1/4] Add support for compatibility classes

Care has been taken to not break user-space compatibility. I have also
updated libsensors and sensors-detect already to look for i2c adapters
in /sys/bus/i2c/devices rather than /sys/class/i2c-adapter. I am not
aware of other user-space applications or libraries using
/sys/class/i2c-adapter, but if you do please tell me.
Improvements are possible on the power management side, but I did not
have the time to deal with this now, so this is left for later.
