regulator: add warning flags
Add 'warning' level events and error flags to regulator core. Current regulator core notifications are used to inform consumers about errors where HW is misbehaving in such way it is assumed to be broken/unrecoverable. There are PMICs which are designed for system(s) that may have use for regulator indications sent before HW is damaged so that some board/consumer specific recovery-event can be performed while continuing most of the normal operations. Add new WARNING level events and notifications to be used for that purpose.
