[Why] Power improvement over DCN314, but also addresses a functional issue where plane_state remains uncleared on pipes that aren't actually active. [How] Update the check to allow for zero streams to be treated as z8 allow. Update the check to remove plane count on the active stream case. Z8 will still be blocked based on stutter duration, which is likely to be the case for most multi plane configurations.

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.
