drm/i915: extract intel_combo_phy.h from i915_drv.h It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.

drm/i915/icl: Factor out combo PHY lane power setup helper Factor out the combo PHY lane power configuration code to a separate helper; it will be also needed by the next patch adding the same configuration for DDI ports. Add support for DDI ports and lane reversal as preparation for the next patch. The PWR_DOWN_LN_1 value is unspecified in the BSpec register description so remove it. v2: - Fix up the wrong assumption that the encodings are the same for DDI and DSI ports. (Jani) v3: - Use intel_ instead of icl_ prefix. (Jani) - Add required headers to intel_combo_phy.h after the upstream header refactoring.
