drm: rcar-du: Use drmm_encoder_alloc() to manage encoder

The encoder allocation was converted to a DRM managed resource at the
same time as the addition of a new helper drmm_encoder_alloc() which
simplifies the same process.

Convert the custom drm managed resource allocation of the encoder
with the helper to simplify the implementation, and prevent hitting a
WARN_ON() due to the handling the drm_encoder_init() call directly
without registering a .destroy() function op.
