* Function: ODM_TxPwrTrackAdjust88E()
*
* Overview: 88E we can not write 0xc80/c94/c4c/ 0xa2x. Instead of write TX agc.
* No matter OFDM & CCK use the same method.
*
* Revised History:
* When Who Remark
* 04/23/2012 MHC Create Version 0.
* 04/23/2012 MHC Adjust TX agc directly not throughput BB digital.
