Subject: [PATCH v2 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.

Changes in v2:
- Renamed symbols in defconfig (Laurent)
- Added missing Kbuild file (Laurent, LKP)
- Renamed guarding defines in include files.
- Dropped mentions of two removed functions.
