As Event Specific Interrupt message format is not defined in UFSHCI JEDEC specs, and the ESI handling highly depends on how the format is designed, hence add a vendor specific ops such that SoC vendors can configure their own ESI handlers. If ESI vops is not provided or returning error, go with the legacy (central) interrupt way.
