jiabin d42361e3d1 [Master port] Add haptic channel mask. This patch ports a change to the HAL interfaces done in master in order to have the same Audio common HAL interface in both AOSP and master. This is needed as the Bluetooth HAL uses the audio common HAL and needs to be frozen in the same state in both AOSP and MASTER.

Directory structure of the audio HIDL related code.
