drm/mediatek: mtk_dpi: Open-code drm_simple_encoder_init()

Browse Source 
The helper drm_simple_encoder_init() is a trivial wrapper around
drm_encoder_init() that only provides a static drm_encoder_funcs with
.destroy set to drm_encoder_cleanup(). Open-code the initialization
with a driver-specific instance of drm_encoder_funcs and remove the
dependency on drm_simple_kms_helper.
