ath11k: add string type to search board data in board-2.bin for WCN6855

Browse Source 
commit fc95d10ac41d75c14a81afcc8722333d8b2cf80f upstream.

Currently ath11k only support 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 PCIe bus chip in
board-2.bin. For WCN6855, it is not enough to distinguish all different
chips.

This is to add a new string type which include bus, chip id, board id,
vendor, device, subsystem-vendor and subsystem-device for WCN6855.

ath11k will first load board-2.bin and search in it for the board data
with the above parameters, if matched one board data, then download it
to firmware, if not matched any one, then ath11k will download the file
board.bin to firmware.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
