Ville Syrjälä 2f051f6774 drm/i915/fbc: Align FBC segments to 512B on glk+
Apply the same 512 byte FBC segment alignment to glk+ as we use
on skl+. The only real difference is that we now have a dedicated
register for the FBC override stride. Not 100% sure which
platforms really need the 512B alignment, but it's easiest
to just do it on everything.

Also the hardware no longer seems to misclaculate the CFB stride
for linear, so we can omit the use of the override stride for
linear unless the stride is misaligned.

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.
