This prepares the driver for further changes that will drop struct pwm_chip chip from struct pwm_sifive_ddata. Use the pwm_chip as driver data instead of the pwm_sifive_ddata to get access to the pwm_chip in pwm_sifive_remove() without using ddata->chip. In the clock rate notifier it's not possible to get the pwm_chip without adding a pointer to this to struct pwm_sifive_ddata. Instead of that add a parent device pointer which is all that is needed there.

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.
