Laurent Pinchart 381ddfe478 drm: rcar-du: Hardcode encoders types to DRM_MODE_ENCODER_NONE
Unlike the connector type, the encoder type is unused by userspace. As
it is equally unused in the driver, except in a single location where
the connector type can be used instead, hardcode it to
DRM_MODE_ENCODER_NONE. This allow removing all code that tries to
determine (unsuccessfully in case a bridge is used) the encoder type.
