The DF Indirect Access method allows for "Broadcast" accesses in which case no specific instance is targeted. Add support using a reserved instance ID of 0xFF to indicate a broadcast access. Set the FICAA register appropriately. Define helpers functions for instance and broadcast reads and use them where appropriate. Drop the "amd_" prefix since these functions are all static.

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.
