scsi: ufs: core: Add Event Specific Interrupt configuration vendor specific ops
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.
