Series add platform check in event manager driver |

Commit Message

Buddhabhatti, Jay Dec. 19, 2023, 5:50 a.m. UTC 
  Some error event IDs for Versal and Versal NET are different.
Both the platforms should access their respective error event
IDs so use sub_family_code to check for platform and check
error IDs for respective platforms. The family code is passed
via platform data to avoid platform detection again.
Platform data is setup when even driver is registered.
