Make struct meson_pwm_channel accessible from struct meson_pwm. PWM core has a limitation: per-channel data can only be set after pwmchip_add() is called. However, pwmchip_add() internally calls pwm_ops.get_state(). If pwm_ops.get_state() needs access to the per-channel data it has to obtain it from struct pwm_chip and struct pwm_device's hwpwm information. Add a struct meson_pwm_channel for each PWM channel to struct meson_pwm so the pwm_ops.get_state() callback can be implemented as it needs access to the clock from struct meson_pwm_channel.

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.
