The context of each engine starts with a 4k memory space for the "Per-process HW status page" (PPHWSP). In xe_gt_lrc_size(), we have been implicitly accounting for that page in the switch statement on the engine class. Since the PPHWSP is common to all engines, let's extract that into it's own assignment. That makes the context structure more explicit in the code and aligns better with the descriptions in Bspec. Another advantage of keeping it separate is that now the sizes used in the switch statement match the sizes we calculate engine-specific context images, which have their own Bspec pages.

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 reStructuredText 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.
