ASoC: amd: acp: Fix acp_common_hw_ops declaration error

Fix acp_common_hw_ops declaration error by adding static and
remove export symbol.
sparse: symbol 'acp_common_hw_ops' was not declared. Should it be static?

Fixes: 8ae746f ("ASoC: amd: acp: Implement acp_common_hw_ops support for acp platforms")
