[Intel-gfx] [RFC 1/7] drm/i915: Move around funcs related to eDP PPS

[Vandana Kannan]

Making ironlake_get_pp_control & vlv_power_sequencer_pipe non-static, to be
used in future patches.
vlv_power_sequencer_pipe should return only pipe, need not set PPS
registers again.
Moving calls to init PPS data and registers to edp_init_connector instead of
having a if(edp) in dp_init_connector.
