dts: spl_wakeup: Remove all workarounds in the spl wakeup logic

We coded few workarounds in special wakeup logic to handle the
buggy firmware. Now that is fixed remove them as they break the
special wakeup protocol. As per the spec we should not de-assert
beofre assert is complete. So follow this protocol.
