Subject: [PATCH 237/255] drm: bridge: dw-hdmi: Remove unneeded arguments to
 bind/unbind functions

The master argument isn't used. The data argument, a void pointer, is
used by the bind function only where it's cast to a drm_device pointer,
which can easily be obtained from the encoder argument instead. Remove
them.
