My patch 24fc32b3 ("ath6kl: add ath6kl_bmi_write_hi32()") caused a regression
in ath6kl_upload_board_file() and the board_address variable was not
properly initialised in some cases:
ath6kl/init.c:1068:6: warning: ‘board_address’ may be used uninitialized
in this function
Most likely this broke ar6004 support but I can't test that right now.

Without this change, SDIO shuts down due to CRC error during
