I2C_COMPAT has been considered deprecated for 15 years now.
Therefore make it default n, before we remove support for it in the
near future. In addition warn any potential user of the old ABI.

Heiner Kallweit (2):
  i2c: core: Switch I2C_COMPAT to default n
  driver core: class: warn if a compatibility class is registered
