[ Upstream commit 31ed8da1c8e5e504710bb36863700e3389f8fc81 ] In the current code, we enable a widget core when it is set up and disable it when it is freed. This is problematic with IPC4 because widget free is essentially a NOP and all widgets are freed in the firmware when the pipeline is deleted. This results in a crash during pipeline deletion when one of it's widgets is scheduled to run on a secondary core and is powered off when widget is freed. So, change the logic to enable all cores needed by all the modules in a pipeline when the pipeline widget is set up and disable them after the pipeline widget is freed.

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.
