[PATCH v6 5/9] drm/mali: use drmm_writeback_connector_init()

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

The driver uses drm_writeback_connector_init() instead of its drmm
counterpart, but it doesn't perform the job queue cleanup (neither
manually nor by calling drm_writeback_connector_cleanup()). On the
contrary, the drmm_writeback_connector_init() function ensures the
proper cleanup of the job queue.

Use drmm_plain_encoder_alloc() to allocate simple encoder and
drmm_writeback_connector_init() in order to initialize writeback
connector instance.
