[PATCH] wifi: ath12k: Allow driver initialization for WoW unsupported devices

[Rameshkumar Sundaram]

Currently during driver initialization, mac registration is allowed
only for devices that advertise WMI_TLV_SERVICE_WOW, but QCN9274
doesn't support WoW and hence mac registration is aborted and driver
is de-initialized.

Allow mac registration to proceed without WoW Support for devices
that don't advertise WMI_TLV_SERVICE_WOW.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
