Priyanka Dandamudi b8d70702de drm/xe/xe_exec_queue: Add check for access counter granularity
Add conditional check for access counter granularity.
This check will return -EINVAL if granularity is beyond 64M
which is a hardware limitation.

v2: Defined
XE_ACC_GRANULARITY_128K 0
XE_ACC_GRANULARITY_2M 1
XE_ACC_GRANULARITY_16M 2
XE_ACC_GRANULARITY_64M 3
as part of uAPI.
So, that user can also use it.(Oak)

v3: Move uAPI to proper location and give proper
documentation.(Brian, Oak)

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.
