Update the HTT_TCL_METADATA version to the latest version (2)
as the bit definitions have changed a little to support more
features. This new version allows the host to submit a packet with
more information to the firmware. Firmware uses this additional
information to do special processing for certain frames.
All the firmware binaries available in upstream/public are compatible with
this HTT version update.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
