From: Wen Gong <quic_wgong@quicinc.com>

Currently ath12k only supports string type with bus, chip id and board id
such as "bus=ahb,qmi-chip-id=1,qmi-board-id=4" for AHB bus chip and
"bus=pci,qmi-chip-id=0,qmi-board-id=255" for PCI bus chip in board-2.bin.
For WCN7850, it is not enough to distinguish all different chips.

Add a new string type which includes bus, chip id, board id, vendor,
device, subsystem-vendor and subsystem-device for WCN7850.

ath12k will first load board-2.bin and searches in it for the board data
with the above parameters. If matched with one board data, ath12k downloads
it to firmware. And if not, downloads board.bin instead.

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