Ilkka Koskinen 05d6f6d346 perf/arm-cmn: Add more bits to child node address offset field
CMN-600 uses bits [27:0] for child node address offset while bits [30:28]
are required to be zero.

For CMN-650, the child node address offset field has been increased
to include bits [29:0] while leaving only bit 30 set to zero.

Let's include the missing two bits and assume older implementations
comply with the spec and set bits [29:28] to 0.

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.
