Add L3SQCREG5 as part of HW recommended settings. The recommended value in Bspec is 00e0007f. For Xe2-LPG, bits 23:21 don't exist anymore, but it's confirmed with HW engineers that setting them doesn't do anything. They still exist on the media GT, Xe2-LPM, but they are already they are already set as per HW default value. So for Xe2 platform, the only bits that need to be set are 9:0 since HW's default is 0x1ff and the recommended value is 0x7f. Unlike most registers, which have the same relative offset on both the primary and media GT, this register has a different base offset on the media GT. On MTL the register only exists for the primary (graphics) GT, so there's no need to program it on the media gt. Also, it's part of the RCS engine's context, so it needs to be added as a LRC workaround.

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.
