kohaku: Always return BP_YES for battery presence for board id 1
For kohaku board id 1, there is a known issue which prevents in
getting battery presence signal correctly. This change returns BP_YES
if the board id reads out as 1. In all other cases, it returns
BP_NOT_SURE to allow baseboard to read gpio to determine battery
present state.
