Atm the port -> DDI and AUX power domain mapping is specified by relying
on the aliasing of the platform specific intel_display_power_domain enum
values. For instance D12+ platforms refer to the 'D' port and power
domain instances, which doesn't match the bspec terminology, on these
platforms the corresponding port is TC1. To make it clear what
port/domain the code refers to add a mapping between them which matches
the bspec terms on different display versions.
This also allows for removing the aliasing in enum values in a follow-up
patch.
v2: Add the functions to intel_display_power.c, use
intel_display_power_ prefix.

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.
