wifi: ath12k: fix preferred hardware mode calculation

For single pdev device like WCN7850/QCC2072, preferred_hw_mode is
initialized to WMI_HOST_HW_MODE_SINGLE. Later when firmware sends
supported modes to host, each mode is compared with the initial one
and if the priority of the new mode is higher, update the parameter
and store mode capability.

For WCN7850, this does not result in issue, as one of the supported
mode indeed has a higher priority. However the only available mode of
QCC2072 at this stage is WMI_HOST_HW_MODE_SINGLE, which fails the
comparison, hence mode capability is not stored. Subsequently driver
initialization fails.

Fix it by accepting a mode with the same priority.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3
