ASoC: amd: vangogh: Add check for acp config flags in vangogh platform

Browse Source 
We have SOF and generic ACP support enabled for Vangogh platform
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 Vangogh based machines. If no flag is
specified probe and register older platform device.
