ASoC: amd: acp: SND_SOC_AMD_ACP_COMMON should depend on X86 && PCI

All configuration symbols for AMD Audio ACP conponents depend on X86 &&
PCI, except for SND_SOC_AMD_ACP_COMMON.  Add a dependency on X86 && PCI
to SND_SOC_AMD_ACP_COMMON, to prevent asking the user about AMD Audio
ACP support when configuring a kernel without X86 or PCI support.
