The EPP tracing is done by the caller today, but this precludes the information about whether the CPPC request has changed. Move it into the update_perf and set_epp functions and include information about whether the request has changed from the last one. amd_pstate_update_perf() and amd_pstate_set_epp() now require the policy as an argument instead of the cpudata.

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 reStructuredText 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.
