wifi: ath12k: Enable MLO for single split-phy PCI device

Browse Source 
The single split-phy PCI device can perform multi-link operation (MLO)
within its own radio, and the MLO-supporting firmware also supports MLO
for split-phy PCI devices.

Therefore, enable MLO for the single split-phy PCI device.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
