Add a data pointer to the genpd_power_state struct, to allow a genpd backend driver to store per-state specific data. To introduce the pointer, change the way genpd deals with freeing of the corresponding allocated data. More precisely, clarify the responsibility of whom that shall free the data, by adding a ->free_states() callback to the generic_pm_domain structure. The one allocating the data will be expected to set the callback, to allow genpd to invoke it from genpd_remove().

README
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.
