Due to special ACPI requirements, the ACPI table must be obtained before downloading the board data file. Therefore, adjust the timing for accessing the ACPI table accordingly. This patch will not affect QCN9274, because only WCN7850 supports ACPI.

To address this issue, obtain the string of the ACPI data filename extension and use it as part of the string to search for the board data file from board-2.bin. This patch will not affect QCN9274, because only WCN7850 supports ACPI.
