Factor out functions to get/put the AUX_IO power domain for the main link on DDI ports. While at it clarify the corresponding code comment. No functional change. v2: - s/(get/put)_aux_power_for_main_link/main_link_aux_power_domain_(get/put) (Jani) - Clarify in the code comment that AUX_IO is needed only by TypeC besides eDP/PSR. v3: - Rebased on checking intel_encoder_can_psr() instead of crtc->has_psr. v4: - Don't call fetch_and_zero() with side-effect during variable declaration.

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.
