Add support for grouping cores based on the device-tree classification. - The last domain in the associativity domains always refers to the core. - If primary reference domain happens to be the penultimate domain in the associativity domains device-tree property, then there are no coregroups. However if its not a penultimate domain, then there are coregroups. There can be more than one coregroup. For now we would be interested in the last or the smallest coregroups, i.e one sub-group per DIE. Currently there are no firmwares that are exposing this grouping. Hence allow the basis for grouping to be abstract. Once the firmware starts using this grouping, code would be added to detect the type of grouping and adjust the sd domain flags 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.
