Add debug statistics collection support. The statistics is available via debugfs in '/sys/kernel/debug/mc/stats', it shows percent of memory controller utilization for each memory client. This information is intended to help with debugging of memory performance issues, it already was proven to be useful by helping to improve memory bandwidth management of the display driver.

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.
