Leaf Hill BSP supports 2 types of audio configurations.
By defaults, BSP will compiled legacy HD-Audio feature,
users can set "AUDIO_FEATURES" in local.conf when they
want Intel SSP Audio feature.
Both audio features are unique and they are mutually exclusive.
AUDIO_FEATURES = "ssp" in local.conf is up to users to turn on
or off depends on their use cases.
