[PATCH] drm/virtio: Replace deprecated drm_simple_encoder_init()

[Davide Bonatto <bonatto.davide@gmail.com>]

drm_simple_encoder_init() is deprecated as it introduces an unnecessary
intermediate layer between atomic modesetting and DRM drivers.

Inline the helper call in virtgpu_display by defining
virtio_gpu_encoder_funcs with the default drm_encoder_cleanup callback,
and migrate directly to drm_encoder_init()
