soc/amd/stoneyridge|mbs: Define SOC_AMD_STONEYRIDGE symbol

Make a new Kconfig symbol for using soc//stoneyridge.  This code also
supports Prairie Falcon is backward-compatible with Carrizo and Merlin
Falcon.

Although Bettong uses Carrizo, it does not currently rely on stoneyridge
source, so it is unaffected by this change.
