Subject: [PATCH 2/2] drm/vkms: Remove <drm/drm_simple_kms_helper.h> include

The driver doesn't use simple-KMS helpers to set a simple display pipeline
but it only uses the drm_simple_encoder_init() helper from simple-KMS that
initializes and encoder.

That helper is just a wrapper of drm_encoder_init(), but passing a struct
drm_encoder_funcs that sets the .destroy handler to drm_encoder_cleanup().

Since the <drm/drm_simple_kms_helper.h> header is only included for this
helper and because the connector is initialized with drm_connector_init()
as well, do the same for the encoder and drop the header include.
