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.
