Matt Roper 8b449f1c44 drm/i915/pvc: Extract stepping information from PCI revid
For PVC, the base die and compute tile have separate stepping values
that we need to track; we'll use the existing graphics_step field to
represent the compute tile stepping and add a new 'basedie_step' field.

Unlike past platforms, steppings for these components are represented by
specific bitfields within the PCI revision ID, and we shouldn't make
assumptions about the non-CT, non-BD bits staying 0.  Let's update our
stepping code accordingly.

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.
