For 6000 series and up, additional enhanced regulatory tx power limitation information is added to EEPROM image. In order to setup the tx power limitation per channel correctly. Read the enhanced tx power information from EEPROM image and update accordingly. The information is provided per SISO (a,b,c) chain based, it also has information for both MIMO2 and MIMO3. For tx power regulatory limitation, take the highest number from all the chains and update. Also update tx_power_user_lmt to the highest power supported by any channels and chains Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
