From: Ryan Hsu ryanhsu@qca.qualcomm.com

[ Upstream commit d2e202c06ca42d353d95df12437740921a6d05b5 ]

With command to get board_id from otp, in the case of following

boot get otp board id result 0x00000000 board_id 0 chip_id 0 boot using board name 'bus=pci,bmi-chip-id=0,bmi-board-id=0" ... failed to fetch board data for bus=pci,bmi-chip-id=0,bmi-board-id=0 from ath10k/QCA6174/hw3.0/board-2.bin

The invalid board_id=0 will be used as index to search in the board-2.bin.

Ignore the case with board_id=0, as it means the otp is not carrying the board id information.
