ASoC: amd: Add check for acp config flags
[ Upstream commit bddcfb0802eb69b0f51293eab5db33d344c0262f ]
We have SOF and generic ACP support enabled for Rembrandt and
pheonix platforms on some machines. Since we have same PCI id
used for probing, add check for machine configuration flag to
avoid conflict with newer pci drivers. Such machine flag has
been initialized via dmi match on few Chrome machines. If no
flag is specified probe and register older platform device.
