wifi: ath12k: check hardware major version for WCN7850

Browse source 
This is to check the hardware major version for WCN7850 so only
supported hardware is initialized. Now only WCN7850 with major
version 2 is supported.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
