wifi: ath12k: disable QMI PHY capability learn in split-phy QCN9274
QMI PHY capability learn is used to get PHY count information to
support single/multi link operation (SLO/MLO) configuration. The
QCN9274 dualmac firmware currently do not support SLO/MLO, if two
PHYs are within the same chip. Due to this firmware crashes in
split-phy QCN9274, while bringing up AP with MLO parameter enabled
in QMI host capability request message.
The QMI PHY capability learn is not required for split-phy QCN9274,
if SLO/MLO is not supported within the same chip. Hence, disable QMI
PHY capability learn support in split-phy QCN9274.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
