Subject: [PATCH v3 0/2] drm/nouveau: remove drm_encoder_slave interface

The nouveau driver is the only user of the drm_encoder_slave interface.
Demote it from KMS helpers module to the nouveau driver itself, moving
corresponding I2C encoders to be handled by nouveau driver too.

Ideally those two drivers should be converted to the drm_bridge
interface, but it's unclear if it's worth spending time on that.
