intel/kunimitsu: Set BOOT_BEEP gpio to a default lo
The BOOT_BEEP gpio is used to activate the buffer which isolates the I2S signals from PCH while doing a beep from depthcharge. It needs to be lo to deactivate the buffer for audio playback from OS. BUG=chrome-os-partner:47124 BRANCH=None TEST=boot depthcharge & test beep with devbeep. Boot OS and test audio playback.
