isci: Add support for user parameters in SCIC layer

Add support for the following parameters in SCIC:

     /**
       * This field specifies the NOTIFY (ENABLE SPIN UP) primitive
       * insertion frequency for this phy index.
       */
      u32  notify_enable_spin_up_insertion_frequency;

      /**
       * This method specifies the number of transmitted DWORDs within which
       * to transmit a single ALIGN primitive.  This value applies regardless
       * of what type of device is attached or connection state.  A value of
       * 0 indicates that no ALIGN primitives will be inserted.
       */
      u16  align_insertion_frequency;

      /**
       * This method specifies the number of transmitted DWORDs within which
       * to transmit 2 ALIGN primitives.  This applies for SAS connections
       * only.  A minimum value of 3 is required for this field.
