intel_dp_panel_power_sequencer and intel_dp_panel_power_sequence_registers
have been replaced by equivalent code in intel_panel.c
Making changes to remove these functions and refs to it.
vlv_power_sequencer_pipe() should return only pipe. panel power
sequencer functions need not be called from here ?
