c9fd91668d drm/i915: add single combo phy init/unit functions
Work on the principle that files should prefer not to expose platform
specific functions.

bd60a56290 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.

d5f9db2c2a 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.
