drm/radeon/kms: unify i2c handling
Previously we added i2c buses as needed when enumerating connectors power management, etc. This only exposed the actual buses used and could have lead to the same buse getting created more than once if one buses was used for more than one purpose. This patch sets up all i2c buses on the card in one place and users of the buses just point back to the one instance.
