Currently auto-hibernate is activated if host supports auto-hibern8 capability. However error-handling is not implemented, which makes the feature somewhat risky. If either "Hibernate Enter" or "Hibernate Exit" fail during auto-hibernate flow, the corresponding interrupt "UIC_HIBERNATE_ENTER" or "UIC_HIBERNATE_EXIT" shall be raised according to UFS specification. This patch adds auto-hibernate error-handling: - Monitor "Hibernate Enter" and "Hibernate Exit" interrupts after auto-hibernate feature is activated. - If a failure happens, trigger error-handling just like "manual-hibernate" failure and apply the same recovery flow: schedule UFS error handler in ufshcd_check_errors(), and then do host reset and restore in UFS error handler.
