fmd: Add support for reading BMI counters from US

Technical Details :  Add support for the following BMI counters
and make them available to the DPA stats interface in the
User Space:

 e_FM_PORT_COUNTERS_DISCARD_FRAME,
    /* BMI stat counter */
 e_FM_PORT_COUNTERS_RX_BAD_FRAME,
    /* BMI Rx stat counter */
 e_FM_PORT_COUNTERS_RX_LARGE_FRAME,
    /* BMI Rx stat counter */
 e_FM_PORT_COUNTERS_RX_LIST_DMA_ERR,
   /* BMI Rx OP stat counter */
 e_FM_PORT_COUNTERS_RX_OUT_OF_BUFFERS_DISCARD,
   /* BMI Rx OP stat counter */
 e_FM_PORT_COUNTERS_WRED_DISCARD,
   /* BMI OP stat counter */

 @Function      FM_PORT_GetBmiCounters

 @Description   Read port's BMI stat counters and place them into
                a designated structure of counters.

 @Param[in]     h_FmPort    A handle to a FM Port module.
 @Param[out]    p_BmiStats  counters structure
