[PATCH v1] drm/mediatek: mtk_dsi: Open-code drm_simple_encoder_init()

The drm_simple_encoder_init() helper is deprecated because it adds an
intermediate abstraction layer that only wraps drm_encoder_init() with
an empty or minimal drm_encoder_funcs struct.

Replace drm_simple_encoder_init() with explicit calls to drm_encoder_init()
and define driver-specific drm_encoder_funcs carrying the cleanup callback.
