Currently, mlo_capable_flags is set to zero if dualmac device is detected based on One Time Programmable (OTP) register value. This is not generic and in future dualmac devices may support Single Link Operation (SLO) and Multi Link Operation (MLO). Thus, set mlo_capable_flags based on 'single_chip_mlo_support' parameter from QMI PHY capability response message from the firmware. Also, add check on mlo_capable_flags to disable MLO parameter in the host capability QMI request message. If the firmware does not respond with this optional parameter 'single_chip_mlo_support' in QMI PHY capability response, default ab->mlo_capable_flags is used.
