ASoC: SOF: amd: fix for firmware reload failure after playback
Setting ACP ACLK as clock source when ACP enters D0 state causing
firmware load failure as mentioned in below scenario.

- Load snd_sof_amd_rembrandt
- Play or Record audio
- Stop audio
- Unload snd_sof_amd_rembrandt
- Reload snd_sof_amd_rembrandt

If acp_clkmux_sel register field is set, then clock source will be
set to ACP ACLK when ACP enters D0 state.

During stream stop, if there is no active stream is running then
acp firmware will set the ACP ACLK value to zero.

When driver is reloaded and clock source is selected as ACP ACLK,
as ACP ACLK is programmed to zero, firmware loading will fail.

For RMB platform, remove the clock mux selection field so that
ACP will use internal clock source when ACP enters D0 state.

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.
