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.
