cryp: Session handling for software context

 - Add a session id to the software crypto context in ux500 crypto
   driver.

 - Add a static global session id which is a counter that increases when
   a new job is started (it is ok that this variable loop back to
   zero when it reach the maximum value).

 - These session id's will be used to decide if the hardware registers
   needs be restored or not for continous jobs. As a result we gain
   performance when we don't need to restore hardware registers.
