This prepares the driver for further changes that will make it harder to determine the pwm_chip from a given ehrpwm_pwm_chip. To just not have to do that, rework ehrpwm_pwm_save_context() and ehrpwm_pwm_restore_context() take a pwm_chip. Also use the pwm_chip as driver data instead of the ehrpwm_pwm_chip.

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.
