ASoC: sof: amd: fix for firmware reload failure in Vangogh platform

[ Upstream commit f2038c12e8133bf4c6bd4d1127a23310d55d9e21 ]

Setting ACP ACLK as clock source when ACP enters D0 state causing
firmware load failure, as per design clock source should be internal
clock.

Remove acp_clkmux_sel field so that ACP will use internal clock
source when ACP enters into D0 state.
