if someone has same spare time,
this driver need a bit more love ...

SO far i can see in rtl92ee_phy_iq_calibrate:
* IQK_MATRIX_REG_NUM should be used instead 8 hardcoded.
* the for-loop in the beginning is obfuscating that it sets  simply final_candidate

this can be cleaned:
      reg_e94 = result[final_candidate][0];
      rtlphy->reg_e94 = reg_e94;
      reg_e9c = result[final_candidate][1];
      rtlphy->reg_e9c = reg_e9c;

only reg_e94, reg_ea4 is used later ?
