The DSI power domain was missing from BXT power well 1 definitions,
failing to get the power well for DSI transcoders. As pipe A is in the
same power well as DSI transcoders, the problem should only occur with
pipes B and C.

This should superseed [1], but a change will be required in
haswell_get_pipe_config() or [2] to check the DSI power domain.
