[PATCH 2/6] drm/arm/komeda : change driver to use drm_writeback_connector.base pointer

[Kandpal Suraj <suraj.kandpal@xxxxxxxxx>]

Making changes to komeda driver because we had to change
drm_writeback_connector.base into a pointer the reason for which is
expained in the Patch (drm: add writeback pointers to drm_connector).
