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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
