soc/amd/stoneyridge: add a romstage hook for mainboards
There wasn't previously a way for Stoney platforms to run mainboard specific code in romstage. This adds an early call for configuration and passes along whether the system is currently resuming from S3. BUG=b:77921345 TEST=Build, verify that weak function implementation gets called.
