[PATCH v2 08/15] drm/imx: remove dependency on DRM simple helpers

[Diogo Silva]

The simple KMS helpers are deprecated because they only add an
intermediate layer between drivers and atomic modesetting.

Open-code drm_simple_encoder_init() by calling drm_encoder_init()
directly and providing driver-local drm_encoder_funcs.
