wifi: ath12k: support MLO as well if single_chip_mlo_support flag is set

Browse Source 
Currently firmware MLO capability is validated via firmware IE, however
WCN7850 firmware does not support this method but instead advertises
MLO by single_chip_mlo_support bit in QMI phy capability message.

Change to consider single_chip_mlo_support bit as well for MLO capability
validation.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00209-QCAHKSWPL_SILICONZ-1
