[PATCH 1/4] drm/i915/pmdemand: convert to_intel_pmdemand_state() to a function

[Jani Nikula]

In preparation for making struct intel_pmdemand_state an opaque type,
convert to_intel_pmdemand_state() to a function.

This is the simplest change. There could be other alternatives.

Outside of intel_pmdemand.c, this is only used to convert
display.pmdemand.obj.state to struct intel_pmdemand_state *. Maybe we
could just pass the global object or state pointer instead? Or we could
have a function to get the current state from, say, struct
intel_display? What we currently have is a bit cumbersome.
