Let's add a copy of the active_pipes bitmask into the cdclk_state. While this is duplicating a bit of information we may already have elsewhere, I think it's worth it to decopule the cdclk stuff from whatever else wants to use that bitmask. Also we want to get rid of all the old ad-hoc global state which is what the current bitmask is, so this removes one obstacle. The one extra thing we have to remember is write locking the cdclk state whenever the bitmask changes.

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.
