Correct the implementation trying to detect MTL PCH with
the MTL fake PCH id.
On MTL, both the North Display (NDE) and South Display (SDE) functionality
reside on the same die (the SoC die in this case), unlike many past
platforms where the SDE was on a separate PCH die. The code is (badly)
structured today in a way that assumes the SDE is always on the PCH for
modern platforms, so on platforms where we don't actually need to identify
the PCH to figure out how the SDE behaves (i.e., all DG1/2 GPUs as well as
MTL and LNL),we've been assigning a "fake PCH" as a quickhack that allows
us to avoid restructuring a bunch of the code.we've been assigning a
"fake PCH" as a quick hack that allows us to avoid restructuring a bunch

Removed unused macros of LNL amd MTL as well.

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.
