Khaled Almahallawy 5e4c16fe08 drm/i915/cx0: Only clear/set the Pipe Reset bit of the PHY Lanes Owned 
Currently, with MFD/pin assignment D, the driver clears the pipe reset bit
of lane 1 which is not owned by display. This causes the display
to block S0iX.

By not clearing this bit for lane 1 and keeping whatever default, S0ix
started to work. This is already what the driver does at the end
of the phy lane reset sequence (Step#8)

Fixes: 619a06dba6 ("drm/i915/mtl: Reset only one lane in case of MFD")

README 

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.
