Based on AsicAdjustTxPower function from vendor driver (2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO) limit per rate TX power values we program into TX_PWR_CFG_ registers. Note that on some configurations (devices/rates) is allowed to use bigger values than 0xc, but we use safe maximum value for now. Further work need to be done to allow use bigger values than 0xc.
