ASoC: amd: yc: Decrease level of error message

On a number of platforms that contain acp3x controller a new ERR level
message is showing up:

`acp6x pci device not found`

This is because ACP3x and ACP6x share same PCI ID but can be identified
by PCI revision.  As this is expected behavior for a system with ACP3x
decrease message to debug.
