[ Upstream commit c66995ae403073212f5ba60d2079003866c6e130 ]
Please apply to 6.10

The "Speaker Volume" control was being defined using four hardcoded magic
numbers. There are #defines in the cs35l56.h header for these numbers, so
change the code to use the defined constants.

Backport Note:
Identical to upstream commit. This was originally thought to be only a
cosmetic issue (the user can simply reduce the volume) but for some complex
audio topologies with SOF Audio DSP + CS42L43 + multiple CS35L56 it has
turned out to be not obvious to the user what the problem actually is and
what to do to fix it. As support for these topologies went into 6.10 we
would like this commit to be backported into 6.10.
