S0ix issues and Cirrus Amp on HP Elitebook 845 G10

Hi,

my HP Elitebook 845 G10 has issues with S0ix deep sleep which seem to be somehow related to the Cirrus AMP. The following log entry appears right before the issue occurs:

2023-09-12 21:03:27,588 DEBUG: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Failed to read MBOX STS: -121 2023-09-12 21:03:27,588 DEBUG: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.1: Failed to read MBOX STS: -121

I have already asked at AMD's gitlab regarding the s0ix issues, but we could not find a solution. See https://gitlab.freedesktop.org/drm/amd/-/issues/2808#note_2082084 for logs and different tests and kernels
