wifi: ath12k: set mlo_capable_flags based on QMI PHY capability

Browse Source 
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.
