mb/google/poppy: Allow variants to provide event info at runtime

This change adds a variant callback to read google_chromeec_event_info
from variant at runtime to allow override of any events based on
factors like board id.

This callback is used in ramstage and smm to get
google_chromeec_event_info structure for performing various actions
like setting masks and logging wake events from EC.
