From 1133af5aea588a58043244a4ecb5ce511b310356 Mon Sep 17 00:00:00 2001

Subject: [PATCH] wifi: ath11k: add chip id board name while searching
board-2.bin for WCN6855
Sometimes board-2.bin does not have the board data which matched the
parameters such as bus type, vendor, device, subsystem-vendor,
subsystem-device, qmi-chip-id and qmi-board-id, then wlan will load fail.
Hence add another type which only matches the bus type and qmi-chip-id,
then the ratio of missing board data reduced.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
