Lucas De Marchi 1878fce8de drm/i915: keep track of used entries in MOCS table
Instead of considering we have defined entries for any index in the
table, let's keep track of the ones we explicitly defined. This will
allow Gen 11 to have it's new table defined in which we have holes of
undefined entries.

Repeated comments about the meaning of undefined entries were removed
since they are overly verbose and copy-pasted in several functions: now
the definition is in the top only.

v2: add helper function to get the index (from Chris)

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.
