drm/arm/hdlcd: replace drm->dev_private with drm_to_hdlcd_priv() 

Using drm_device->dev_private is deprecated. Since we've switched to
devm_drm_dev_alloc(), struct drm_device is now embedded in struct
hdlcd_drm_private, hence we can use container_of() to get the struct
drm_device instance instead.
