drm/i915: Adjust intel_modeset_pipe_config() & co. calling convention

Use the state+crtc calling convention for intel_modeset_pipe_config()
and othere related functions. Many of these need the full atomic state
anyway so passing it all the way through is just nicer than having to
worry about whether it can actually be extracted from eg. the crtc
state passed in.
