mb/google/geralt: Add NAU8318 support for Geralt

Add a config "USE_NAU8318" to enable NAU8318 support.

NAU8318 is another speaker used in Geralt. NAU8318 supports beep
function via GPIO control. So we configure the GPIO pins and pass them
to the payload.

BUG=b:250459803
BRANCH=none
TEST=Verify beep function through CLI in depthcharge successfully.
