disable deep sleep when Iota LEDB is on TI's Iota chip docs say that CLK13M must be running in order for LEDB to work, and practical experience on Mot C139 which uses Iota LEDB for its keypad backlight concurs: if Calypso enters deep sleep while the keypad backlight is turned on, the light flickers visibly as the chipset goes into and out of deep sleep. TI's original L1 sleep manager code had logic to disable deep sleep when LT_Status() returns nonzero, but that function only works for B-Sample and C-Sample LT, always returns 0 on BOARD 41 - no check of Iota LEDB status anywhere. Change this code for our current hardware: disable deep sleep when Iota LEDB has been turned on through LLS.

 *
 *  The L2RCOP entity can take a primitive away from the relay entity. This
 *  happens, when there are not enough data to be sent and the timer expires.
 *  In this case the L2RCOP entity takes the half ready primitive and sends
 *  it to RLP
 *
 *  The handling of the ring buffer is as follows:
 *
 *  *   The L2RCOP entity allocates a number of primitives. The slot in which
 *      the next primitive has to be allocated is indicated by the alloc index.
 *      Besides the primitive, which is just beeing filled by the relay
 *      entity, there should be one complete empty primitive ready. This
 *      means that the alloc index is at least by two greater than the write
 *      index, unless the L2RCOP entity can not provide new primitives quick
 *      enough.
 *  *   The relay entity writes data into the primitive indicated by the write
 *      index.
 *  *   When a primitive is filled up, the relay advances the write pointer and
 *      sends a DTI2_DATA_REQ primitive to the L2RCOP entity.
 *  *   When the L2RCOP entity receives the DTI2_DATA_REQ primitive it takes the
 *      primitive at the read position (which usually is identical with the
 *      previous write position), and advances the read index.
 *      Then it sends the primitive to the lower layer,
 *      and checks, if a new primitive has to be allocated. 
 *  *   When a timeout occurs, the L2RCOP entity locks the complete buffer.
 *      If no primitive is in the ring buffer (i.e read = write = alloc), a
 *      new primitive is allocated and sent as an empty primitive to the lower
 *      layer. If a completely filled primitive is in the buffer (i.e write /=
 *      read), this primitive is sent in the regular way. Otherwise there is
 *      a partial filled or empty primitive in the buffer (write /= alloc).
 *      Then this primitive is sent and the write index is incremented. In the
 *      case of a partial filled primitive the last uncompleted L2R status
 *      octet has to be finished before sending the primitive. Finally it
 *      is checked, if a new primitive has to be allocated.
 *  *   When a break is requested from the upper layer, the data are discarded
 *      and a BREAK signal is put into a new primitive and sent to the lower layer.
 *      Then the buffer is new initialised.
